Field of the Invention The present invention relates to an electronic component and a wire used therefor, a method of manufacturing the same, and a method of manufacturing the electronic component using the wire. More particularly, it relates to a capacitor including a sealing body having a through hole through which a wire is inserted. I: Prior Art 3 Background of the Invention 10 FIG. 17 is a cross-sectional view showing an aluminum electrolytic capacitor of an electronic component, and FIG. 18 is a perspective view of a wire used in the aluminum electrolytic capacitor, and FIG. 19 is a cross-sectional view of the wire. As shown in Fig. 17, the aluminum electrolytic capacitor includes a capacitor element 6, which is a functional element, a lead wire 1, a casing 7, and a sealing body 8. The lead wire 1 is led out from the capacitor 15 element 6, and the bottomed cylindrical case 7 houses the capacitor element 6, and the sealing body 8 is provided with a through hole 8a through which the lead wire 1 is inserted. The sealing member 8 is disposed in the opening of the casing 7, and is extended by the extension processing portion 7a provided on the outer peripheral surface of the casing 7, thereby closing the opening of the casing 7. As shown in Fig. 8, the wire 1 has an extraction electrode 20 2 made of an aluminum wire round bar 2, a cap 4, and a flat portion 2e. As shown in Fig. 19, the cap 4 covers the leading end 2a of the lead electrode 2 end. The flat portion 2e is connected to the capacitor element 6. The cap 4 covering the front end portion 2a functions as a connection with the circuit board 10. The cap 4 is selected to use a material that is easy to weld. As described above, the aluminum electrolytic capacitor is used to cover the lead wire 1 having the private substructure from the cover 4 in the front end portion 2a 201003693. Compared to directly at the front end. By splicing the wire terminal, the shape of the joint between the tip end portion 2a and the terminal can be reduced. Therefore, the quality of the pipe is easy, the joint quality is stable, and the aluminum electrolytic capacitor with high reliability can be provided. Such an aluminum electrolytic capacitor 5 is disclosed, for example, in Japanese Laid-Open Patent Publication No. SHO 63-178318. However, in the conventional aluminum electrolytic capacitor, when the cap 4 is covered and fitted to the distal end portion 2a by a method such as press-fitting, the appearance of the cap 4 is often deformed, and burrs are generated at the end of the opening. Then, when the lead wire is inserted through the through hole 8a of the sealing body 8, a gap is generated between the outer peripheral surface of the cap 4 and the inner surface of the through hole 8a. Moreover, the burrs generated by the wires 1 cause scratches in the through holes, and the electrolyte is easily leaked to cause poor sealing reliability. Further, when the wire 1 is inserted through the through hole 8a, the burr generated at the wire 1 falls off and falls: next to the capacitor element 6, causing a short circuit problem.

The cap is attached to the front end of the electrode. The functional component and the aforementioned wire are included. Bow 丨. With the foregoing structure, it is possible to prevent the appearance of the cap covering the appearance of the cap. 201003693 Moreover, the outer diameter of the front end of the lead-out electrode in front of the cap is smaller than the inner diameter of the cap. And the cap is covered on the front end of the lead electrode and then pressed from the outer surface of the cap, whereby the cap does not deform, and the front end of the lead end made of the soft material of the cap is Deformation. Then, the outer surface of the leading end of the lead electrode can be crimped to the inner surface of the cap. Therefore, when the cap is covered on the front end portion of the lead-out electrode, the inner peripheral edge portion of the open end portion of the cap does not bite the outer peripheral portion of the tip end portion of the electrode-end. As a result, 遂 can suppress the occurrence of burrs at the open end of the cap.

Mode for Carrying Out the Invention Hereinafter, various embodiments of the present invention will be described with reference to the drawings. In the respective embodiments, the same components as those in the previous embodiments are denoted by the same reference numerals, and the description thereof will be omitted, and only the different portions will be described. (Embodiment 1) FIG. 1 is a cross-sectional view showing the structure of an aluminum-electric 5 de-capacitor as an example of an electronic component according to an embodiment of the present invention. Fig. 2 is a perspective view showing the expanded portion of the capacitor element of the functional element of the aluminum electrolytic capacitor. 3A to 3E are cross-sectional views showing respective manufacturing steps of the wires used in the electrolytic capacitor. First, the structure of the aluminum electrolytic capacitor of the present embodiment and the wire used therefor will be described with reference to Figs. 1 and 2 . As shown in the figure, the aluminum electrolytic 10 container includes: a capacitor element 16, which is a functional element, a casing 17, a sealing body 18, and an insulating fine sub-board 19. The electric device element 16 is connected to a pair of wires 11. The housing 17 having a bottomed shape houses the capacitor element 丨6. The sealing body 8 is provided with a through hole 18a through which the wire is inserted. The sealing body 18 blocks the opening of the housing 17. The insulating terminal plate 19 is provided with a through hole 19a, and the outer surface of the insulating terminal plate 19 is provided with a groove portion 15b. The through hole 19a accommodates the terminal 15 of the lead wire 11 led out from the sealing body 18. The groove portion 19b accommodates the fin 15 that is inserted through the through hole 19a and bent in a direction slightly orthogonal. The insulating terminal plate 19 is disposed to be connected to the opening of the casing 17. The lead wire 11 has a cylindrical metal lead electrode 12', a metal cap 14, and a linear terminal 15. The cap 14 is formed of a material 20 which is harder than the lead electrode 2 and covers the front end of one end of the lead electrode 12. The terminal 15 is attached to the outer surface of the cap 14. The outer surface of the front end portion 12c is press-contacted with the inner surface of the cap 14, and at least a part of the crimping interface is formed with a metal diffusion layer 12d for engaging the rain. The leading end of the lead electrode connected to the capacitor element 16 is processed into a flat shape to form a flat portion 126. 10 201003693 Further, the cap 14 is formed of a material harder than the lead electrode 12, and it is shown here that the cap 14 is relatively larger in durability against the shape deformation than the front end portion 12c. Further, when an aluminum wire round bar is used as the material of the extraction electrode 12, the material of the base material of the cap 14 may be selected from aluminum hard iron, nickel, and iron-nickel alloy. Further, in addition to the material type of the base material of the cap 14, the factors relating to the strength such as the thickness of each portion of the cap 14 should be appropriately considered. Further, the inner surface of the cap 14 may be provided with a bell layer to make the joint with the front end portion i2c stronger. The mineral deposit may use, for example, tin, nickel, copper or the like. For example, when the lead electrode 12 uses an aluminum wire round bar and the base material of the cap 丨 4 uses iron, an iron ore layer of copper or nickel may be provided on the surface of the iron base material. Such a coating should preferably be provided on at least the inner surface of the cap 14. The terminal 15 is made of a metal plate or a wire made of a metal substrate such as iron, nickel, copper, iron alloy or copper alloy. Further, a plating layer of 15 layers may be formed on the outer surface of the terminal 15. For example, in order to be connected to the circuit substrate 20, a tin alloy in which tin, tin, indium, lead, or the like is added to tin or tin may be used as the plating layer. Further, as shown in Fig. 2, the lead electrode 12 is bonded to the flat portion i2e by an ultrasonic foil welding or a pressure bonding or the like, and an anode foil crucible 6a and a cathode foil crucible 6b are bonded, respectively. The anode case 16a and the cathode foil 16b are each formed of a valve action metal such as aluminum. The electric grid element 16 of the power bin b element is formed by separating the anode foil "a and the cathode foil 16b from the separator 16c and winding them together. Here, the functional element refers to the active and passive control of the electrical function. The entire device is, for example, a capacitor element in the case of a battery generator, a battery element or an electrode group in the case of a battery, and a semiconductor element in the case of a semiconductor. 201003693 The casing 17 is made of a metal such as a tin or a tin alloy. The casing 17 houses an electrolyte (not shown) such as a capacitor element 16, an electrolytic solution, and/or a solid conductive polymer. The opening portion of the casing 17 is provided by an extension processing portion 17a provided on one of the outer peripheral surfaces of the casing 17. The generated stress is 'blocked|arranged inside the opening portion by a sealing body 18° composed of a resilient body, and the through hole 18a of the sealing body 18, and the terminal 15, the cap 14, and the extraction electrode 12 of the wire 11 are arranged in this order. Further, the extraction electrode 12 is in contact with the inner surface of the through hole 18a, and the terminal 15 is led out from the sealing body 18. The diameter of the through hole 18a is set to be the same as or slightly smaller than the outer diameter of the extraction electrode 12. , The stress generated by the extension processing portion Ha in the sealing member 18 is sealed between the sealing member 18 and the extraction electrode 12. The insulating terminal plate 19 abuts against the opening of the casing 17. Further, the terminal 15 is inserted through the insulation. The through hole 19a of the terminal block 19 is bent in a substantially right-angle direction. Further, the front end portion of the terminal 15 is housed in the groove 15 portion 19b provided on the surface of the insulating terminal plate 19. The insulating terminal plate 19 is made of polyethylene, polypropylene, and poly pairs. A thermoplastic resin such as ethylene phthalate or a liquid crystal polymer, or a thermosetting resin such as a resin or an epoxy resin is formed. Further, the terminal 15 is more likely to form a solder fillet when mounted on the circuit board 2 by soldering. Alternatively, the terminal 15 may be stored in the groove portion 19b in a portion of the groove portion 19b by press working, etc. Next, a method of manufacturing the wire bundle will be described with reference to FIGS. 3A to 3E. As shown in Fig. 3A, the outer peripheral surface of the extraction electrode 12 is held by the clamp jig 13a, and the front end portion 12a before the deformation of the extraction electrode 12-end is exposed. Then, the cap Η is covered on the front end portion 12a (step A) Leading out 12 201003693 Extreme 12: The cap (4) is formed by a metal plate of a hard shell from a lead-out electrode and formed into an opening shape by press working. The inner diameter of the opening of the cover a cover 14 is set to be closer to the front end portion. The outer diameter is large. Because of this, the outer surface of the end portion 12a and the inner surface of the cap 14 are not pressed: 'there is a state in which there is a gap between each other. 'Next, as in the first As shown in Fig. 3B, the front end portion 12a is shaped by the front end portion 12a to form the front end portion 12e. The money is crimped to the inner surface of the front cover portion 12c (step b). The specific implementation of the B step is as follows. W firstly presses the inner bottom surface of the cap 14 covering the front end portion 12a to the upper surface of the front end portion 2 = and mechanically presses the outer surface of the cap μ. By this force pressing operation, the cap 14 is not deformed, but the shape of the j end portion 12a is greatly deformed by the fact that the cap is made of a soft material. As a result, the front end portion 12C' is formed and the outer surface of the front end portion 12" and the inner surface of the cap 14 are in contact with each other. Further, the distal end portion I2a is deformed by the pressurization to become the distal end portion 12c, and is pressed against the cap 15 so as to be unloaded, and the outer diameter of the main portion of the lead electrode 12 and the distal end portion 12c are removed. There is a gap between the outer diameters. Further, when the outer surface of the cap 14 is mechanically pressurized, for example, the following method can be applied. For example, there is a method of placing the pin on the outer bottom surface of the cap 14 and pressing it, and applying a tool such as a key to the outer surface of the cap 14 to instantaneously attack the square r+-X. To apply these methods, one of the outer bottom surfaces of the cap 14 is provided with a flat portion. Further, it is preferable to provide a guiding member which is connected to the outer periphery of the cap 14 in the direction in which the cap 14 is pressed. Thereby, mechanically holding the outer bottom surface of the cap 14 can easily make the central axis of the cap 14 coincide with the central axis 13 201003693 of the extraction electrode 12. "then" as shown in Fig. 3c, the electrodes for the fusion are respectively connected to the outer bottom of the brim 14 and the outlet electrode 12. Then, the electric arc connection, the electric reconnection and the like are used to electrically connect the cap and the lead. ^Apply heat treatment step 5). In addition, the heat treatment may be applied from the outside of the cap 借 by means of a gas burner, laser, electromagnetic induction, etc. The cap U and the extraction electrode 12 are fused at the interface of the splicing, and the metal diffusion layer 12d is formed at least partially, and the metal diffusion layer (3) omits the metal material constituting the cap 14 and the extraction electrode 12. Next, as shown in the first thorn, "the sub- 15 is attached to the outer surface of the cap 14 (step D). Specifically, the linear terminal 15 is first attached to the outer surface of the cap, and then the welding electrode 13C is respectively The terminal portion 15 and the body portion of the extraction electrode 12 are connected to each other. The terminal 15 and the cap 14 are joined by a method such as resistance welding by the welding electrode 13c. The shape of the terminal 15 may be a plate shape or the like in addition to the linear shape. After that, as shown in FIG. 3E, the cover 14 is not covered. The other end end portion 12b of the discharge electrode 12 is deformed to form a flat portion 12e (step e). As shown in Fig. 2, the flat portion 12e will be filled by the gap between the capacitor element 16 and the bow-out electrode 12. The method is connected to the anode foil 16a and the cathode casing 20 16b by a method such as ultrasonic wave. The E step is specifically carried out in the following manner: the outer surface of the front end portion i2b is sandwiched and pressed, and rolled to form a plate parallel to the axial direction of the extraction electrode 12. The flat portion 12e is formed by cutting the circumference to a predetermined width and length. Further, the front end portion 12b may be other than a flat shape, and may be deformed and processed into a shape suitable for forming an electrode of the element to be connected. Etc. As described in the above-mentioned 14 201003693, the wire u can be made by the steps A, B, C, d, E. Next, an aluminum electrolytic capacitor for manufacturing an example of the electronic component of the embodiment using the wire 说明 will be described. First, as shown in Fig. 2, the anode case 10a, the cathode case, and the divided piece 16e are cut into a predetermined width and length. The anode (10) surface has a dielectric layer of an oxide film. A~E steps made A pair of wires u are respectively connected to the anode foil 16a and the cathode foil i6b by caulking and ultrasonic waves in the flat portion 12e thereof. Thereafter, the separator foil 16b is interposed with the anode foil, for example, and the cathode foil 16b, and is wound into a roll. The outer peripheral side surface is wound and fixed by an insulating tape or the like (not shown), thereby forming the capacitor element 16. Further, the electrode for constituting the functional element is the same as the anode foil 16a and the cathode foil 16b. In addition to the winding, a plurality of foil-like laminates, a sintered body, and the like may be laminated. Next, as shown in Fig. 1, the capacitor element 16 and the electrolyte containing 15 electrolyte are housed in the casing 17. Then, one of the pair of lead wires 11 drawn from the capacitor element 16 is inserted into one of the pair of through holes i8a of the sealing body 18. In this state, the sealing body 18 is placed in the opening of the casing 17. Alternatively, it can be used to gather. A solid electrolyte such as a conductive polymer represented by a polypyrrole or a polycemente may be used instead of the electrolytic solution ‘and both of them may be used. After that, the extension processing portion 17a is tightened from the outer circumferential side of the casing ,, and the opening of the casing 17 is closed. Thereafter, the insulating terminal plate 19 is disposed to be connected to the opening of the casing 17. Then, the terminal 15 of the pair of wires 11 is led out from the outside of the sealing body 18, and is inserted into one of the pair of through-holes 19a of the insulating terminal plate 19. 15 201003693 ^ Thereafter, the terminal 15 projecting from the through hole 19a is folded into a right angle "in a direction opposite to each other" and housed in the groove portion b provided on the outer surface of the insulating terminal plate I9 - to prepare a surface mount Type Ming electrolytic capacitors. When the front end of the terminal 15 of the groove portion 19b of the insulating terminal plate 19 is to be formed into a flat shape, the terminal 15 is processed into a plate shape by press working or the like before the terminal 15 is inserted into the through hole 19a. In addition, when the electrolyte contained in the capacitor element 16 is a solid electrolyte such as a conductive polymer, an insulating outer resin formed of an epoxy resin or the like may be used as the exterior material instead of the casing 17 and the sealing member 18. At this time, the exterior tree 1 resin covers the capacitor element 16 and leads the terminal 15 of the wire 11 to the outside of the exterior resin. Further, after the opening of the casing 17 is sealed, or after the insulating terminal plate 19 is mounted, a voltage is appropriately applied between the terminals 15, and re-formation is performed. As described above, in the lead wire 1 of the present embodiment and the method of manufacturing the same, the cap 15 cover 14 is formed of a material harder than the lead electrode 12. Thereby, it is possible to prevent the appearance of the cap 14 from being deformed when the cover 14 is covered by the front end portion i2a. Further, the outer diameter of the front end portion 12a before the cap 14 is covered is smaller than the inner diameter of the cap 14. Further, after the cap 14 is covered by the distal end portion 12a, the cap 14 is pressed without being deformed from the bottom surface of the cap 14, and the distal end portion 12a is deformed into the distal end portion 20c. Thus, the outer surface of the front end portion 12c can be crimped to the inner surface of the cap. Therefore, when the cap 14 is covered by the distal end portion 12a, the inner peripheral portion of the opening end portion of the cap 14 does not bite the outer peripheral portion of the distal end portion 12a. In this way, the burrs generated at the open end of the cap 14 due to such bite marks can be suppressed. Since the generation of the burrs of the wires 11 can be suppressed as described above, it is possible to prevent the wires 16 201003693 η from being short-circuited when they are inserted through the through holes 18a. Moreover, the burr can be suppressed, and the burr is caused by the member 16 and the squeegee 18 is smeared in the through hole 18a. Therefore, the sealing airtightness can be improved, and the reliability of the electronic component can be improved. The front end portion m of the extraction electrode U and the cap 14 of the portion 12a are mechanically entangled by a different moth-type crimping method, and further, the pressure is 10

Thereby, the degree of reinforcement can be enhanced, thereby improving the bonding. Calling, the electronic parts of the material, and even under the harsh _ 贞 钱 , , , , 依然 依然 依然 依然 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The guide point U is also used in the material of the material of the wire U ′ cap M, which should be higher than the material used for the material (4). For example, when the lead electrode 12 is made of aluminum, the substrate of the cover 14 is made of a metal having a higher melting point. If this is the case, it is possible to prevent the shape of the over-axis of the cap from causing burrs and projections on the outer surface of the cap 15 14 during the heat treatment of the step C. Further, when the lead electrode 12 is used, the metal used for the base material of the cap is preferably composed of a metal single body of copper, nickel or iron, an alloy containing copper, nickel, and iron. When the metals are below the melting point of the coating, an alloy in a liquid phase state can be formed. Therefore, by the heat treatment, the end of the extraction electrode 20 12 formed by the wire rod is formed. [The interface between the U2c and the cap 14 is pressed, and the metal diffusion layer 12d is easily formed to improve the joint strength. Further, in order to easily form a metal diffusion layer, a metal having a higher melting point than aluminum should be provided at least on the inner side of the cap 14, or may be provided in the form of a base material or a mineral coating layer of the cap 14. In this way, the electronic component using the wire u can prevent the open defect caused by the breakage of the wire 11 even in the environment where the severe vibration load of 17 201003693 is applied, and can also prevent the burrs and protrusions on the outer surface of the cap 14 Such as the short circuit caused by the short circuit and the low airtightness of the seal. Further, when the interface between the bonding cap 14 and the front end portion 12C of the extraction electrode 12 is crimped by heat treatment, it is preferable to adjust the thickness of the cap 14, the material, and the extent of covering the extraction electrode 12. This not only prevents the shape of the cap from being excessively melted, but also improves the joint strength. In order to melt the interface between the cap 14 and the front end portion 12c, the thickness of the bottom surface and the outer side surface of the cap 14 is preferably uniform. 10 When the tin deposit is applied to the surface of the cap 14, and the lead electrode 12 is used for the lead electrode 12, the metal diffusion layer 12d exhibits a state in which aluminum and tin are diffused. The state of diffusion of the aluminum and tin, in general, is liable to produce tin whiskers when placed under conditions of high temperature, high humidity or thermal cycling. When the diffusion of aluminum and tin exposes the outer surface of the electronic component, the growth of the tin whisker sometimes causes a short circuit problem. However, in the wire U, the metal diffusion layer (3) is stored inside the cap 并未 and does not expose the outside. Even if the metal diffusion layer (3) contains the touch, the tin whisker does not grow outside, and the wire is used. The electronic parts can suppress the short circuit caused by tin whiskers. In addition, the metal mixed with the metal diffusion layer 12d can also be a combination of Ilu and tin outside the metal, as long as it is easy to produce whiskers 20 The same effect can be obtained. The outer diameter of the cap 14 is larger than the outer diameter of the lead electrode 12, and in the wire U, there is a step $ (not shown). By the step ', the mark sealing body 18 can be used. The wire 11 of the through hole (10) is strongly engaged. In this way, the wire 11 is prevented from being displaced toward the inside of the casing 17 and the load of the connection between the wire n and the capacitor element 16 is caused by the connection of the 201003693. Therefore, By using the electronic component of the wire u, it is possible to prevent the disconnection or short circuit caused by the abnormality of the connection between the wire Η and the capacitor element 16 and the increase of the leakage current. 5 10 15 20 In addition, the through hole i8a of the sealing body 18 has an aperture, preferably only Insert the wire ^ upper cap 14 The portion of the position is set to be larger in advance, whereby the step formed by the difference in outer diameter between the cap μ and the extraction electrode can reduce the gap generated between the wire u and the through hole 18a, and improve the airtightness of the seal. It is preferable that the outer periphery of the cap f 14 has a curved surface whose outer diameter is enlarged along the outer bottom of the cap 14 toward the opening end side. When the wire u is inserted into the through hole 18a, at least the cap 14 and the through hole receive the inner surface. The contact portion may have such a curved surface, for example, a dome shape, a conical shape, a truncated cone shape, etc. If the cap member 4 has such a curved surface, the action of the wire u when inserted into the through hole 18a can be reduced. The load of the wires 11 is therefore prevented from being deformed by the wires U or - the case where the wires n are inserted from each other to cause a load on the connection portion between the wire capacitor elements b. Thus, the electronic parts of the wires U can be used to prevent the wires. When the connection between the capacitor element 16 and the capacitor element 16 is abnormal, the riding or short-circuiting, the leakage current is increased, etc. Further, if the material of the terminal 15 constituting the wire 11 is, for example, an iron-based substrate, the cap should be selected from iron, recorded, Iron nickel "Substrate." In addition, if the end button is a copper beryllium substrate, the cap 14 should preferably be a steel or copper alloy substrate. That is, if the difference in electric resistance between the dice 15 and the cap 14 is small, the joint strength between the t-piece 15 and the cap 14 can be maintained at the time of electric resistance refining, and the occurrence of a shape such as a burr can be suppressed. Moreover, even if the thermal energy of the outer surface of the cap 14 and the terminal 15 is transmitted to the edge of the 19 201003693 between the cap 14 and the front end portion 12c, the burrs and the red __ are generated due to the front end of the interface. The portion 12e is covered by the cap 14 'will not be exposed to the outside. This is a sub-part, which can be caused by the wire (1)/pass; (1), the burr of the electric wire of the wire smashing, etc., and the through hole 1 (4) of the shank body 18 are airtight and reliable. Further, the terminal 15 is connected to the material of the cap 14 by the cap 14 (four) of the terminal 15 and the material of the cap 14. Therefore, the metal material is connected. For example, = combination use is easy to dissolve with each other... #雷接接接接接15 Fish cap 10 15 20 Cover 14 When the material constituting the terminal 15 or the hot material is selected to be the same or similar to 2 bU. Thereby, the joint strength can be reduced to prevent the joint portion between the terminal 15 and the cap U from being excessively glazed into a shape*. Thus, the electronic parts of the wire u are used. The manufacturing process is caused by the fact that the harsh vibrational material 15 is misaligned, and the shape of the burrs and protrusions of the joint between the material 15 and the cap is not "slow." Figure 3 illustrates the manufacturing steps prior to the step. Figures 4A and 4B are cross-sectional views of the various conductors and steps of the above-mentioned wires u. ^ As shown in Figure 4A, preferably before step A, The step of forming the planar chamfered portion 22f on the outer peripheral portion of the front end portion 12a of the front end portion 12a of the bow electrode 12 is added. If the F step is added, when the cap 14 is covered on the front end portion 123, the cover is attached. The inner peripheral edge portion of the open end portion of the opening 14 is less likely to contact the outer peripheral portion of the front end portion. Therefore, it is possible to suppress the occurrence of burrs at the open end portion of the cap 14. Further, in the step A shown in Fig. 4B, it is preferable to use the cap. The door 20 of the cover 14 201003693 is provided with a corner portion 24a on the inner peripheral portion of the end portion. Therefore, the inner peripheral edge portion of the open end portion of the cap 14 is less likely to contact the outer peripheral portion of the tip end portion 12a of the one end of the lead electrode 12.遂 can suppress the occurrence of burrs. In addition, the shape of the corner portions 22f, 24a can also be curved In the planar shape, it is possible to obtain the same effect as the planar one. Therefore, by using the electronic component of the wire 11, it is possible to suppress a short circuit caused by a burr or the like caused by the through hole 18a through which the wire 11 is inserted, and to improve the sealing gas. (Embodiment 2) FIG. 5 is a cross-sectional view showing a configuration of an aluminum electrolytic capacitor which is an example of an electronic component according to Embodiment 2 of the present invention. FIG. 6 is a capacitor element of a functional component of the aluminum electrolytic capacitor. Fig. 7A to Fig. 7G are cross-sectional views showing respective manufacturing steps of the lead wire used in the aluminum electrolytic capacitor. First, an aluminum of an example 15 of the electronic component of the present embodiment will be described using Figs. 5 and 6 . The structure of the electrolytic capacitor and the wire used therein is different from that of the aluminum electrolytic capacitor of the first embodiment shown in Fig. 1, in that the tip end portion 32c (after deformation) of the lead electrode 12 constituting the wire 31 is taken out. The main portion of the electrode 12 is thin. Further, the outer diameter difference between the cap 34 covering the distal end portion 32c and the main portion of the extraction electrode 12 is smaller than that of the aluminum electrolytic capacitor of the first embodiment. The method for manufacturing the wire 31 of the present embodiment having the above configuration will be described with reference to FIGS. 7A to 7G. The difference from the first embodiment shown in FIGS. 3A to 3E is shown in FIG. 7C. Before the step A, the step of processing the outer end portion 32a (before the deformation 21 201003693) of the lead electrode 12 to be thinned as shown in Fig. 7A is included (there are fewer steps). In the G step, the mold can be used. The front end portion 32a is processed to be thinner than the main body portion of the lead electrode 12 by a method of pressurizing, etc. Further, at the A dream after the G step, the cap 34 is covered on the distal end portion 5 32a. When B is less than the second step shown in Fig. 7D, the outer surface of the cap 34 is mechanically pressurized until the outer surface of the end portion 32c is brought into contact with the inner surface of the cap 34. Therefore, in order to prevent the opening end portion of the cap 34 from coming into contact with the step 10 caused by the difference between the outer diameter of the main portion of the lead electrode 12 and the outer diameter of the front end portion 32a during the pressurization of the step B, it is necessary to first The processing size of the front end portion 32a is set. Further, as shown in Fig. 7B, the flat deangular portion 32f is formed at the outer peripheral portion of the front end portion 32a (step ρ·). Further, it is preferable to form a planar chamfered portion 32g by the outer peripheral edge portion of the step portion which is formed by the difference between the outer diameter of the main portion of the lead electrode 12 and the outer diameter of the distal end portion 32a (step H). 7E to 7G are respectively related to the embodiment iic, D'E steps

Thereby, the gap outside the cap 34 of the electrode 12 can be made. Therefore, similarly to the state 1 of the embodiment 22 201003693, it is possible to suppress a short circuit caused by a burr or the like when the wire 31 is inserted into the through hole 18a of the sealing body 18. Further, when the thickness of the sealing member 18 is thin, it is possible to prevent a gap from being formed between the through hole 18a and the wire 31, thereby improving the hermeticity of the sealing. 5, when the lead wire 31 produced by the additional step is used for the aluminum electrolytic capacitor, the edge of the outer peripheral edge portion of the step portion is generated by the difference between the outer diameter of the main portion of the lead electrode 12 and the outer diameter of the distal end portion 32a. Not an acute angle. Therefore, it is possible to prevent the sealing body 18 on the inner surface of the through hole 18a from being scratched when the lead wire 31 is inserted through the through hole 18a. Thus, leakage of the electrolyte can be suppressed, and the sealing gas 10 can be improved. In addition, the Η step may be additionally performed, either simultaneously with or after the G step, or at the same time as or before the F step. Further, as shown in Fig. 7C, it is preferable to provide the corner portion 34a at the inner peripheral portion of the open end portion of the cap 34. Thereby, the inner peripheral edge portion of the open end portion of the cap 34 is less likely to contact the outer peripheral edge portion of the distal end portion 32a, and the occurrence of 15 burrs at the open end portion of the cap 34 can be suppressed. Further, the shape of the chamfered portions 32f, 32g, and 34a shown in Figs. 7B and 7C may be curved, and the same effect as that of the planar shape can be obtained. Next, different G steps will be described with reference to Figs. 8A and 8B. Fig. 8A and Fig. 8B are cross-sectional views of the manufacturing steps of another example of the conductor 31. Further, in the G step shown in Fig. 8A, the deformed front end portion 42a of the leading end 12 of the lead electrode is processed into a trapezoidal shape (truncated taper). That is, the outer diameter of the foremost end portion of the front end portion 42a is made smaller. In the case of such a shape, when the cap 34 is covered by the distal end portion 42a, the inner peripheral edge portion 23 201003693 of the open end portion of the cap 34 is less likely to contact the outer peripheral edge portion of the distal end portion 42a. Therefore, it is possible to further suppress the occurrence of hair on the open end of the cap 34. Hereinafter, the effects of the present embodiment will be described with reference to specific examples. When the wire 31 was first produced, a |5-line round bar having a diameter of i.3 mm and a purity of 99.99% was used as the body member of the extraction electrode 12. The cap 34 is formed by press-working a plate-shaped base material of iron. The opening of the cap 34 is set to have an outer diameter of 16 mm, an inner diameter of 13 mm, and a length of 0.8 mm to 1.0 mm. Further, the shape of the bottom side of the cap 34 is a circular flat portion having a curved surface at the outer peripheral edge portion and a circular flat surface having a diameter of about 0.3 mm to 1. mm. Further, a surface of the cap 34 is formed with a nickel plating layer having a thickness of 2 μm to 1 〇 # m of copper as a bottom layer. Further, the inner peripheral edge portion of the open end portion of the cap 34 is provided with a flat-shaped chamfered portion 34a. The terminal 15 is made of an iron wire having an outer diameter of 0.6 mm, and a nickel plating layer having a thickness of 2#m to l〇#rn of copper as a bottom layer is formed on the surface thereof. 15 First, at the G step shown in FIG. 7A, the tip end portion 32a of the lead electrode 12 is processed to be thinner than the body portion of the lead electrode 12 and is smaller than the cap 34 by using a mold and pre-pressurizing. The path is small. Specifically, the external control of the front end portion 32a is changed to 1.10 mm. Further, the size of the end portion 32a in the longitudinal direction (the axial direction of the lead electrode 12) is set to be 1.3 mm longer than the length of the cap 34. Further, in the step F shown in Fig. 7B at the same time as the G step, the mold is formed in a peripheral portion of the front end portion 32a to form a planar chamfer portion. Further, in the initial step, the step portion (10) which is formed by the difference between the outer diameter of the main portion of the lead electrode 12 and the outer diameter of the front end portion is formed into a planar chamfer portion. 24 201003693 Next, in the step A shown in Fig. 7C, the outer peripheral surface of the main body portion of the extraction electrode 12 is held by the clamp jig 13a, and the front end portion 32a is exposed. Then, the cap 34 is covered on the front end portion 32a' and the inner bottom surface of the cap 34 is brought into contact with the end surface of the front end portion 32a. 5 Thereafter, at the step B shown in Fig. 70, the outer bottom surface of the cap 14 is mechanically pressurized. At this time, the front end portion 32a is deformed by the inner side of the cap 34, and the outer diameter is increased, and the deformed rear end portion η of the electrode 12 is taken out. The outer surface and the inner surface of the cap 34 are in contact with each other. Next, in the step C shown in Fig. 7E, the welding electrodes Ub are respectively connected to the outer bottom portion of the cap 34 and the main body portion of the extraction electrode 12. Then, the cap 34 and the front end portion 32c are subjected to heat treatment by a resistance dazzling method. At this time, the temperature is raised to the vicinity of the glare of the metal material for the cap 34 and the extraction electrode 12, and the interface between the cap 34 and the front end portion 3 is melted. After that, a metal diffusion layer 32d is formed at the interface, and the surface is expanded to form a metal material constituting the front end portion 32c of the caps 51 and 15. Next, in the step D shown in FIG. 7F, the linear terminal 15 is attached to the outer surface of the cap 34, and the brittle electrode is connected to the body portion of the terminal (9) and the electrode 12, respectively. Join the joint. After 2 ,, in the E step shown in Fig. 7G, the outer end of the other end of the lead electrode 12 is applied to the outside of the side, and the extension is formed into a plate shape in the direction of the axis of the electric rib, and then cut. (4) (4) Forming the riding part A. As mentioned above, the steps of G, F, H, a, b, c 31 ° D, E can be made into wires for the purpose of the wire 31 thus produced and the use of the wire 31 25 201003693 For comparison, the following wires were prepared as comparative samples. The material uses the extraction electrode 12, the cap 34, and the terminal 15 which are interposed with the wire 31. Then, in the step 3A (3+|86), when the tip end portion 32a of one end of the lead electrode 12 is made thinner, the outer circumference becomes larger than the inner diameter of the cap 34. Something two 4_. Therefore, in the case of the step 7C, in order to cover the end portion 32a' of the cap 34, the bottom surface of the mechanical cap cap is pressed, and the bottom surface of the cap 34 is connected to the riding end. As a result, in the step a, the cylindrical surface of the tip end portion and the cap 34 are pressed, so the step B is omitted. 10 The steps other than the above are performed (4). As described above, the wires of the comparative sample can be made by G, F, Η, A, Γ, η ^ _ AL 〇, Ε step 。. The wire made of the above-mentioned wire 31 and the wire of the comparative sample are respectively made into a seal. In the case of using the wire 31, the steps are described with reference to Fig. 5 and Fig. 6. First, the aluminum foil is etched and chemically processed in a boric acid 15 aqueous solution. An oxidized film is formed thereon to form an anode foil 16a. On the other hand, an aluminum foil is etched to form a cathode foil 16b. The flat portion 12e of the wire 31 is press-bonded to the anode foil 16a and the cathode 16b. The separating member 16c of the Manila paper is further interposed between the anode 20 case 163 and the cathode foil 16b, and wound around the anode foil 16a and the cathode foil. 16b forms the capacitor element 16. Next, after the capacitor element 16 is impregnated with the electrolytic solution, it is housed in the bottomed cylindrical case 17 of the name. After that, the sealing body 18 whose main component is butyl rubber is cracked in the case. The opening portion of the body 17. At this time, the pair of wires 31 led out from the capacitor element 26 201003693 16 are inserted into the through hole 18a of the sealing body 18, and the terminal 15 is led out to the outside of the sealing body 18. Then, from the case The outer peripheral surface of the body 17 is subjected to an extension process of the casing 17 and the sealing body 18, and the opening end of the casing 17 is closed. Thereafter, the insulating end 5 sub-plate 19 is abutted against the opening of the casing 17. Further, the terminal 15 led to the outside of the sealing member 18 is inserted into the through hole I9a provided in the insulating terminal plate 19. Finally, the terminal 15 is bent in a substantially right-angle direction and housed in the groove portion 19b provided on the surface of the insulating terminal plate 19. By the above steps, 遂 6.3V, 1500 / / F A surface mount type aluminum electrolytic capacitor. 1) Each of the lead wires 31 and the comparative sample wires were produced, and the number of defective appearances caused by the burrs generated at the open end portions of the caps 34 joined to the lead electrodes 12 was examined. Further, the number of defective products of the tensile strength test of the lead electrode 12 and the cap 34 was also investigated. As a result, the lead wire 31 had no defective appearance and no defective product of the tensile strength test 15. On the other hand, the comparative sample wire was found. There are 200 defective products without the tensile strength test. It is thus known that the wire 31 can ensure the joint strength between the lead electrode 12 and the cap 34, and the cap 34 can be prevented from opening compared to the comparative sample wire. The ends produce a burr. Next, 1000 aluminum electrolytic capacitors using the lead wires 31 and the comparative sample wires were fabricated, and the number of short-circuit defective products occurred in the reflow test was investigated. As a result, the aluminum electrolytic capacitor using the wire 31 did not suffer from a short circuit failure. mouth. On the other hand, five aluminum electrolytic capacitors using comparative sample wires found five defective products. Thus, it is known that the use of the wire 31 prevents short-circuit defects after reflow and improves the reliability of the aluminum electrolytic capacitor.

The capacitor element 56 is formed by winding a pair of metallized crucibles in a state in which the vapor-deposited electrodes 56c and 56d are not in contact with each other in a substantially cylindrical shape. Further, as shown in Fig. 9, the capacitor element 56 has a pair of collector electrodes 56g and 56h on both end faces thereof, and is connected to the vapor deposition electrodes 5&, 15 56d, respectively. Alternatively, a pair of metallized films may be laminated to form a capacitor element of the laminate. Next, a method of manufacturing the wires 51 and 61 will be described with reference to FIGS. 11A to 11B. In the second UASI to the eleventh 11th, the difference from the 7th to the 7thth embodiment of the second embodiment is that the two ends of the extraction electrode 12 are processed and cut. A pair of wires 51, 61. That is, both ends of the extraction electrode 12 are processed at the G F Η step as shown in the figure "A" to form the front end portions 52a, 62a before the deformation which is thinner than the body portion. X, each of the front 29 201003693 end portions and the step portions are machined to form chamfered portions 52g, 52f, 62g, 62f. Then, in the step A shown in Fig. 11B, the caps 34 are respectively covered at the front end portion 52a and the front end portion 62a. Next, in the step B shown in Fig. 11C, the cap 34 is pressed against the extraction electrode 12 to form the distal end portion 52c and the distal end portion 62c, and the electrode 12 and the cap 34 are crimped. Further, at the step C shown in Fig. 11D, metal diffusion layers 52d and 62d are formed. Thereafter, at the step D shown in Fig. 11E, the terminals 15 are respectively connected to the cap 34.

然後，在第11E圖所示D步驟後，第11F圖所示I步驟時， 沿與轴線方向垂直之方向將引出電極12裁斷一分為二。I步 10 驟時，藉切斷器33d裁斷引出電極12之中央附近。如第9圖 所示，若導線51、61之扁平部52e、62e長度相異時，則依 其比例調整裁斷位置即可。最後，在第11G圖所示E步驟 時，形成扁平部52e、62e。如此，藉由G、F、Η、A、B、 C、D、I、E步驟遂可製成導線51、6卜 15 另，I步驟亦可在B步驟或C步驟之後。E步驟亦可在I 步驟之前。 接下來，說明使用導線51、61之本實施形態之電子零 件一例之膜電容器的製造方法。 與第9圖所示實施形態2之鋁電解電容器之製造方法相 20 異之點，在於電容器元件56形成方法不同，以及不需要電 解液等電解質。其餘均與實施形態2相同。 首先，說明電容器元件56之製造方法。如第10圖所示， 在裁成預定寬度之一對介電體膜之一面，分別設蒸鍍電極 56c、56d，又，長度方向之一邊端部則設非蒸鑛部分56a、 30 201003693 56b。 然後，將膜配置積層，使蒸鍍電極56c與蒸鍍電極56d 不相互接觸，且一端之非蒸鍍部分56a與非蒸鍍部分56b相 對。在此狀態下繞捲一對金屬化膜形成略圓筒狀之繞捲 5體。此時，令蒸鍍電極56c、56d自繞捲體之分別端面露出。 之後，於呈略圓筒狀之一對金屬化膜之兩端面，藉由 熔融並噴吹鋁、錫、銅等金屬之熔射法等形成集電極56g、 56h。並且將集電極56g、56h分別連接蒸鍍電極5&、撕。 接著，彎折導線51、61之扁平部52e、62e，並使其等 ίο前端部分分別藉點熔接等方法連接於集電極56§、56h。然 後，將引出電極52、62自繞捲體之同一方向成對引出，形 成電容器元件56。 接下來’將電容器元件56收納於殼體π。此時，在電 容器元件56與殼體17之間設間隙，或者在殼體17之内表面 15配置絕緣材。藉由該等方法令電容器元件56之外表面與殼 體17之内表面不相接觸。 然後’藉與實施形態2相同之方法，利用封口體18封堵 殼體17之開口部’且形成可進行表面貼裝之形狀。 如上所述，使用由蒸鍍電極56c、56d自端面露出之金 20屬化膜構成之電容器元件56時，依然可使用導線51、61。 即，可彎折扁平部52e、62e再連接以構成膜電容器。若使 用導線51 61 ’與實施形態2相同地，可抑制起因於導線$ 1、 61插通封D體18之貫通孔⑽時之咬痕毛邊料成的短路 情形，並提高膜電容器之封口氣密性。 31 201003693 又，本實施形態之導線之製造方法，可有效率地由一 個引出電極12製作出二條導線51、61。換言之，生產性大 為提高。 (實施形態4) 5 第12圖係顯示本發明實施形態4之電子零件一例之鋁 電解電容器之結構的截面圖。第13圖係該鋁電解電容器之 功能元件之電容器元件的展開部分立體圖。 首先，利用第12圖、第13圖來說明本實施形態之電子 零件一例之鋁電解電容器及該鋁電解電容器所用導線之結 10構。如第12圖所示，本實施形態鋁電解電容器與第5圖所示 實施形態2鋁電解電容器相異之點，在於導線71未預先具有 端子75。即’端子75係藉嵌入成形法等，設在配置連接於 殼體17開口部之絕緣端子板79。並且端子75連接於導線71 之帽蓋34。 15 前述鋁電解電容器包含有：電容器元件16、殼體17、 封口體18、及絕緣端子板79。電容器元件16連接有一對導 線71。導線71具有引出電極12和帽蓋34。帽蓋34接合於引 出電極12—端之前端部32c。引出電極12另一端之前端部分 經加工成扁平部12e。依此，導線71具有實施形態2之導線 20 31除去端子15以外的結構。絕緣端子板79具有一對端子， 配置連接於殼體17之開口部。導線71之帽蓋34之外底部， 朝封口體18之貫通孔18a之外部露出。一對帽蓋34之外底面 與設在絕緣端子板79之端子75接合。端子75可連接電路基 板20。 32 201003693 導線71之製法，係實施形態2之導線31之製法中，除不 實施第7F圖所示連接端子15之D步驟以外，其餘均與導線31 一樣地製作。 其次，說明製造使用導線71之本實施形態之銘電解電 5容器的製造方法。首先，如第13圖所示，將陽極箔16a、陰 極·;116b、及分離件16c裁剪成預定寬度和長度。利用填隙 和超音波等方法將導線71之扁平部i2e分別連接於陽極箔 16a與陰極箔16b。之後，以分離件16c中隔於陽極箔16&與 陰極箔16b之間並纏繞成捲筒狀成為略圓筒形。再利用絕緣 10膠帶等（未圖示)停繞固定其外周側面，於是形成電容器元件 16 〇 又，為功能元件之電容器元件16，亦可積層數片陽極 箔16a、陰極箔16b而成。亦可使用燒結體取代陽極箔163、 陰極箔16b。 15 接著，如第12圖所示，將電容器元件16與含有電解質 之電解液一齊收納於殼體17。然後，使自電容器元件16引 出之一對導線71分別插通设於封口體18之一對貫通孔 18a。在此狀態下將封口體18配置於殼體17之開口部。另， 亦可用以聚吡咯、聚塞吩為代表之導電性高分子等固體電 2〇解質來取代電解液，併用該等兩者也可。 之後，自殼體17之外周側面縮緊形成引伸加工部na， 俾封堵殼體17之開口部。此時，使帽蓋34之外表面自封口 體18之貫通孔18a露出。 於後，將絕緣端子板79配置成連接於殼體17之開口 33 201003693 部。又’使藉嵌入成形法等設在絕緣端子板79之一對端子 75之一端端部，接觸自封口體18之貫通孔18a霧出外部之帽 蓋34外表面，並利用熔接等方式加以接合。 此外’若電容器元件16所含電解質為導電性高分子等 5固體電解質時，其外裝材亦可使用環氧樹脂等形成之絕緣 性外裝樹脂，以取代殼體17與封口體18。此時’以外襞樹 脂覆蓋電容器元件16並且將導線71之帽蓋34外表面導出至 該外裝樹脂的外部。 又，當封堵殼體17之開口部後，或者當安裝絕緣端子 10 板79後，適當地於端子75間施加電壓，進行再化成。 依以上結構，由於覆蓋前端部32c之帽蓋34與端子75之 間接合性良好，所以帽蓋34未預先接合有端子75亦無妨。 可在使導線71插通貫通孔18a且令帽蓋34外表面朝外部露 出後，再接合端子75。於是’與實施形態2相同地，可抑制 15 起因於導線71插通貫通孔18a時之毛邊等造成的短路情 形。又，由於可藉嵌入成形法等將端子75預先設在絕緣端 子板79，所以可防止彎曲加工時導致端子75之位置不齊。 (實施形態5) 第14圖係顯示本發明實施形態5之電子零件一例之铭 2〇 電解電容器之結構的截面圖。第15圖係該鋁電解電容器之 1

in Fig. 11E, in the step I shown in Fig. 11F, the extraction electrode 12 is cut in two in a direction perpendicular to the axial direction. At the time of step I, the cutter 33d cuts the vicinity of the center of the extraction electrode 12. As shown in Fig. 9, when the lengths of the flat portions 52e and 62e of the wires 51 and 61 are different, the cutting position can be adjusted in accordance with the ratio. Finally, at the step E shown in Fig. 11G, flat portions 52e, 62e are formed. Thus, the wires 51, 6 can be made by the steps G, F, Η, A, B, C, D, I, E, and the I step can also be after the step B or the C step. The E step can also be preceded by the I step. Next, a method of manufacturing a film capacitor which is an example of the electronic component of the present embodiment using the wires 51 and 61 will be described. The manufacturing method of the aluminum electrolytic capacitor of the second embodiment shown in Fig. 9 is different in that the capacitor element 56 is formed in a different manner and that an electrolyte such as an electrolytic solution is not required. The rest are the same as in the second embodiment. First, a method of manufacturing the capacitor element 56 will be described. As shown in Fig. 10, vapor-deposited electrodes 56c and 56d are provided on one surface of the dielectric film, one of the predetermined widths, and the non-steamed portions 56a, 30 201003693 56b are provided at one end portion in the longitudinal direction. . Then, the film is laminated so that the vapor deposition electrode 56c and the vapor deposition electrode 56d do not contact each other, and the non-vapor-deposited portion 56a at one end is opposed to the non-vapor-deposited portion 56b. In this state, a pair of metallized films are wound to form a substantially cylindrical winding body. At this time, the vapor deposition electrodes 56c and 56d are exposed from the respective end faces of the wound body. Thereafter, the collector electrodes 56g and 56h are formed by melting or blowing a metal such as aluminum, tin or copper by melting and blowing the both end faces of the metallized film. Further, the collector electrodes 56g and 56h are connected to the vapor deposition electrode 5& Next, the flat portions 52e, 62e of the wires 51, 61 are bent, and the front end portions are connected to the collectors 56, 56h by means of spot welding or the like, respectively. Then, the lead electrodes 52, 62 are taken out in the same direction from the wound body to form the capacitor element 56. Next, the capacitor element 56 is housed in the casing π. At this time, a gap is provided between the capacitor element 56 and the casing 17, or an insulating material is disposed on the inner surface 15 of the casing 17. By these methods, the outer surface of the capacitor element 56 is not in contact with the inner surface of the casing 17. Then, in the same manner as in the second embodiment, the opening portion ’ of the casing 17 is closed by the sealing member 18, and a surface mountable shape is formed. As described above, when the capacitor element 56 composed of the gold-based chemical film exposed from the end faces by the vapor deposition electrodes 56c and 56d is used, the wires 51 and 61 can be used. That is, the bendable flat portions 52e, 62e are reconnected to constitute a film capacitor. When the wire 51 61 ' is used in the same manner as in the second embodiment, it is possible to suppress the short-circuiting of the bite burrs caused by the insertion of the wires $1, 61 into the through-holes (10) of the sealing body 18, and to improve the sealing of the film capacitor. Sex. 31 201003693 Further, in the method of manufacturing a lead wire according to the present embodiment, two lead wires 51 and 61 can be efficiently produced from one lead electrode 12. In other words, productivity is greatly improved. (Embodiment 4) FIG. 12 is a cross-sectional view showing the structure of an aluminum electrolytic capacitor which is an example of an electronic component according to Embodiment 4 of the present invention. Fig. 13 is a perspective view showing the expanded portion of the capacitor element of the functional element of the aluminum electrolytic capacitor. First, the aluminum electrolytic capacitor of an example of the electronic component of the present embodiment and the structure of the wire for the aluminum electrolytic capacitor will be described with reference to Figs. 12 and 13 . As shown in Fig. 12, the aluminum electrolytic capacitor of the present embodiment differs from the aluminum electrolytic capacitor of the second embodiment shown in Fig. 5 in that the lead wire 71 does not have the terminal 75 in advance. In other words, the terminal 75 is provided by an insulating terminal plate 79 that is connected to the opening of the casing 17 by an insert molding method or the like. And the terminal 75 is connected to the cap 34 of the wire 71. The aluminum electrolytic capacitor includes a capacitor element 16, a case 17, a sealing body 18, and an insulating terminal plate 79. A pair of wires 71 are connected to the capacitor element 16. The wire 71 has an extraction electrode 12 and a cap 34. The cap 34 is joined to the leading end portion 32c of the lead electrode 12. The other end portion of the lead electrode 12 is processed into a flat portion 12e. Accordingly, the wire 71 has the structure other than the terminal 15 except for the wire 20 31 of the second embodiment. The insulating terminal plate 79 has a pair of terminals that are disposed to be connected to the opening of the casing 17. The outer bottom of the cap 34 of the wire 71 is exposed to the outside of the through hole 18a of the sealing body 18. The outer bottom surface of the pair of caps 34 is joined to the terminal 75 provided on the insulating terminal plate 79. Terminal 75 can be connected to circuit board 20. 32 201003693 The method of manufacturing the wire 71 is the same as that of the wire 31 except that the step D of the connection terminal 15 shown in Fig. 7F is not carried out in the method of manufacturing the wire 31 of the second embodiment. Next, a method of manufacturing the electroplating electric 5 container of the present embodiment using the lead wire 71 will be described. First, as shown in Fig. 13, the anode foil 16a, the cathode·116b, and the separator 16c are cut into a predetermined width and length. The flat portion i2e of the wire 71 is connected to the anode foil 16a and the cathode foil 16b, respectively, by caulking and ultrasonic waves. Thereafter, the separator 16c is interposed between the anode foil 16& and the cathode foil 16b and wound into a roll shape to have a substantially cylindrical shape. Further, the outer peripheral side surface is stopped by the insulating tape 10 (not shown), and the capacitor element 16 is formed. Further, the capacitor element 16 of the functional element can be laminated with a plurality of anode foils 16a and 16b. A sintered body may be used instead of the anode foil 163 and the cathode foil 16b. 15 Next, as shown in Fig. 12, the capacitor element 16 is housed in the casing 17 together with the electrolyte containing the electrolyte. Then, one of the pair of lead wires 71 drawn from the capacitor element 16 is inserted into one of the pair of through holes 18a of the sealing body 18. In this state, the sealing body 18 is placed in the opening of the casing 17. Further, it is also possible to use a solid electric oxime such as a conductive polymer represented by polypyrrole or polycetole instead of the electrolytic solution, and both of them may be used. Thereafter, the outer peripheral side surface of the casing 17 is contracted to form the extension processed portion na, and the opening of the casing 17 is closed. At this time, the outer surface of the cap 34 is exposed from the through hole 18a of the sealing body 18. Thereafter, the insulating terminal plate 79 is disposed to be connected to the opening 33 201003693 of the housing 17. Further, 'the insertion molding method or the like is provided at one end portion of one of the terminals 75 of the insulating terminal plate 79, and the through hole 18a of the self-sealing body 18 is brought into contact with the outer surface of the outer cap 34, and joined by welding or the like. . In addition, when the electrolyte contained in the capacitor element 16 is a solid electrolyte such as a conductive polymer, an insulating outer resin formed of an epoxy resin or the like may be used as the exterior material instead of the casing 17 and the sealing member 18. At this time, the eucalyptus resin covers the capacitor element 16 and leads the outer surface of the cap 34 of the wire 71 to the outside of the exterior resin. Further, after the opening of the casing 17 is sealed, or after the insulating terminal 10 plate 79 is mounted, a voltage is appropriately applied between the terminals 75 to re-form. According to the above configuration, since the joint between the cap 34 covering the distal end portion 32c and the terminal 75 is good, the cap 34 is not bonded to the terminal 75 in advance. The terminal 75 can be joined after the lead wire 71 is inserted through the through hole 18a and the outer surface of the cap 34 is exposed to the outside. Thus, in the same manner as in the second embodiment, it is possible to suppress the short-circuiting condition caused by the burrs or the like when the wire 71 is inserted into the through hole 18a. Further, since the terminal 75 can be previously provided in the insulating terminal plate 79 by the insert molding method or the like, it is possible to prevent the position of the terminal 75 from being uneven during the bending process. (Fifth Embodiment) Fig. 14 is a cross-sectional view showing the structure of an electrolytic capacitor according to an example of an electronic component according to a fifth embodiment of the present invention. Fig. 15 is a perspective view showing an expanded portion of a capacitor element of a force energy element of the aluminum electrolytic capacitor. Figs. 16A to 16F are cross-sectional views showing respective manufacturing steps of the wires used in the aluminum electrolytic capacitor. First, the structure of the unwinding capacitor and the wire used therefor will be described using the fourteenth and fifteenth drawings of the present embodiment. As shown in the fourteenth aspect, the present embodiment differs from the electrolysis capacitor of the second embodiment shown in Fig. 5 in that the conductor (10) is used instead of the wire 3 to constitute the terminal Μ of the wire 81, and is not connected to the « by the dazzle. 84 outside the surface, but with the cap thin body shaping. The method of manufacturing the electric wire used in the electrolytic capacitor of the fifth embodiment of the above configuration will be described with reference to Figs. 16A to 16F. In the Figs. 16A to 16F, the following two points are different from the manufacturing steps of the second embodiment shown in Fig. 7A to Fig. 2; The steps shown in FIG. 16 are performed before or after the steps of g, F, and 所示 shown in the first όβ diagram of the front end portion of the lead electrode 10 I2-end before the deformation of the lead electrode 10 I2-end, as shown in FIG. The outer surface-body formed with the cap 84 of the terminal 85 is formed (the step of the second step is not the step of welding the terminal 85 to the cap 84. In the J step, the base material such as the block iron is added by using the mold. The pressing method is applied to the outer surface of the cap 84 to form the terminal 85. At this time, it is preferable to form the chamfered portion 84a at the end of the mouth. Khan, then, using the cap 84, G, F, h , A, B, e, and wonderful ^ The electronic component of the fifth embodiment is produced - the 34 electrolytic capacitor of the example is used. The wire 20 8i is used. The 16th C, the first, the 16th, and the 16th are respectively displayed. In the step B shown in Fig. 16D, the front end portion 12e is deformed by the inner side of the cap electrode 84 by the inner side of the cap 84, and then the outer surface of the pressing portion 12c and the cap 84 are formed. Inner surface. At this time, the bottom surface of the cap is mechanically pressurized 'and avoids the terminal 85. Since ^*84 35 201003693 C step shown in Fig. 16E At this time, the cap 84 and the extraction electrode i2 are subjected to heat treatment. At this time, the m electric egg bit is connected to the outer surface of the cap 84 other than the position of the terminal 85. Thereby, the metal diffusion layer 32d can be efficiently formed. By replacing the wire 3 with the wire 81 and performing it in the same manner as in the embodiment 2, an electrolytic capacitor is manufactured. As described above, since the terminal-body sand is on the outer surface of the cap, the splicing of the splicing 85 and the cap can be omitted. The step of the cover 84 improves the productivity. Moreover, the unevenness of the shape (four) degree between the terminal 85 and the cap can be reduced to a minimum to improve the connection quality. 10 Λ ^ between the exhaustor 85 and the cap 84 Since the shape of the joint is very low, it is possible to suppress the gap between the sealing body 18 and the wire 81 in the through hole 18a, and to improve the sealing gas. Moreover, the vertical vibration can also improve the vibration resistance of the electronic component. Therefore, it is possible to manufacture electronic components with high sinfulness. = The above-mentioned electronic component of the present invention can prevent the cap from being covered by the cover by forming the towel cover by the bow-out electrode. The appearance of the cap when the tip end of the electrode is deformed «After covering the tip end of the lead-out electrode with the end of the lead-out electrode, the cap will not deform from the outside of the cap, but the end of the electrode will be deformed before the electrode is pulled out. It is crimped to the inner surface of the cap. Therefore, when the towel cover is covered on the front end of the lead electrode, the peripheral edge of the open end of the cap can be prevented from being bitten and pulled out of the outer peripheral end portion of the electrode end end. That is, the cap can be suppressed. The opening end has a burr. The 疋' can suppress the deformation of the cap and the open end of the cap. 201003693 The sealing edge caused by the burrs, etc., has low sealing airtightness and short circuit. Therefore, the present invention is applicable to highly reliable I-generated electronic parts requiring high sealing air tightness and short circuit resistance.
