Patent Document 1: Japanese Patent Application Laid-Open No. 2002-175859 Problem to be Solved by the Invention An electrical contact structure having the above-mentioned insulating substrate and spiral contacts has, for example, a shape as shown in FIG. 17. The above-mentioned electrical contact structure 1 is a structure in which a plurality of spiral contacts 2 are mounted on an insulating base 97422.doc 200527997 board (hereinafter referred to as a base) 3. The base 3 is provided with a plurality of recessed portions (through holes) 3a penetrating from the front surface to the back surface, and the spiral contact 2 is provided on the upper surface of the recessed portion 3a. FIG. 18 is a partially enlarged rear view of the spiral contact 2 in the spiral contact 2 shown in FIG. 17 as viewed from the surface side. As shown in FIG. 18, a conductive portion 丨 0 which is conductively connected to the spiral contact 2 is exposed around the concave portion 3a. The back surface of the conductive portion 11 is the same plane as the back surface of the base 3. The electrical contact structure described above is formed, for example, through each step shown in FIG. 19. In the step of FIG. 19A, a resist layer 5 is formed on the Cu substrate 4 with a pattern 5 a of the spiral contacts 2 formed by exposure and development, and a spiral contact is formed in the pattern 5 a of the resist layer 5. 2. In the step shown in FIG. 19B, after the resist layer 5 is removed, the guide frame 6 made of resin or the like is positioned so that the hole portion 6 a provided in the guide frame 6 faces the spiral contacts 2 exactly. Right, the above-mentioned guide frame 6 is stuck between the base portions 2a of the spiral contacts 2 (see also FIG. 17). Next, in the step of FIG. 19C, the Cu substrate 4 is removed by, for example, etching or the like. The spiral contacts 2 are connected by the above-mentioned guide frame 6. Next, in the step of FIG. 19D, the above-mentioned spiral contact 2 is adhered and fixed to the base 3 by using a conductive adhesive 8 or the like, wherein the position of the base 3 facing the spiral contact 2 is formed. Through-hole 3a. The conductive portion 10 is formed on the inner surface 7b of the through hole 3 & of the base 3 by a sputtering method or the like. 97422.doc 200527997…, and back 'In the step of FIG. 19E, the spiral contact 2 is three-dimensionally formed by using the above-mentioned protruding adjustment member 9. In the step of FIG. 19F, a connection terminal 1 is provided on the back surface side of the base 3 via the conductive adhesive 14. A printed wiring board 12 having a plurality of wiring patterns and other circuit components is provided below the base 3, and the base 3 is fixed to the printed wiring board 12. A counter electrode 13 is provided on the surface of the printed wiring board 12 opposite to the connection terminal 11 provided on the bottom of the base 3, and each of the connection terminals 丨 丨 and each of the opposite electrodes 丨 3 are made through a conductive adhesive or the like. Connected. However, the electrical contact structure 1 obtained through the steps of Figs. 19A to 19F has the following problems. First of all, first, the above-mentioned electrical structure 丨 mainly has a spiral contact 2, a base 3, a guide frame 6, a conducting portion 10, and a connection terminal u, but the electrical contact structure 1 is formed in this way, and the number of parts is large. It will lead to increased production costs. "The abutment 3 is a complex structure with the conductive portion 10 formed by sputtering on the inner surface of the through-hole 3 a. The above-mentioned abutment 3 has a high cost and becomes an electrical contact structure. One of the reasons for the increase in the production cost of the body. First, the spiral contact 2 and the connecting terminal 丨 and the conducting portion 10 are connected to each other via a conductive compound 8 and 14, and the connection The Zhizi 11 and the counter electrode 13 of the printed wiring board 12 are also fixed by using a conductive bulking agent. However, in the bonding and fixing method using a conductive adhesive, it is necessary to heat-bond the parts at this time. If the thermocompression bonding between the above is 97422.doc 200527997, the results will lead to poor continuity and lower reliability between the two parts. Therefore, the thermocompression bonding is performed with high precision. Necessity consideration, do not know It is delicate to manufacture. The first rigid electrical contact structure 1 is not suitable for a small structure. For example, when the spiral contact 1 itself is further miniaturized, it is necessary to reduce the size of the screw contact 1. The through hole on the stage 3 ", but if the through hole 3a is too small, the conductive portion 10 'cannot be formed in the through hole 3a with an appropriate film thickness, thereby becoming an electrical contact structure 1 with poor electrical characteristics. Therefore, the through hole 3 cannot be too small. As a result, even if the spiral contact 1 itself can be formed small, the abutment 3 cannot be formed small. In addition, when the film thickness of the abutment 3 is too thin, the base The strength of the stage 3 itself is reduced, so that the conductive contact cannot be used to connect the screw contact 2 and the connection terminal 11 to the base 3 with good conductivity by thermal compression bonding. Therefore, the miniaturization of the electrical contact structure 1 cannot be further promoted. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a miniaturization and a reduction in the number of parts, particularly compared with the prior art. The electrical contact structure can be connected easily and reliably with a simple structure and its manufacturing method. The present invention relates to an electrical contact structure, which is configured to have an electrical contact portion that is in electrical contact with a contacted object, and a holding body that holds the electrical contact portion, wherein the electrical contact portion is formed by the above The holder is held on the front side of the holder. A concave portion extending to the back is provided on the holder 97422.doc 200527997. A conductive portion is provided in the concave portion. The conductive portion is directly connected to the electrical contact portion. The back side of the holding body is electrically connected to the connected portion. The electrical contact structure of the present Maoming is composed of an electrical contact portion, a holder, and a conductive portion. Compared with the prior art, the number of parts can be reduced, and an electrical contact structure with a simple structure can be obtained. You Bawu first took the necessary abutment and replaced it with a retaining body.

In addition, the present invention relates to a method for manufacturing an electrical contact structure, which is to produce an electrical contact structure having an electrical contact portion that is in electrical contact with a contacted body and a holder that holds the electrical contact portion. It includes: (a) a step of forming an electrical contact portion by electroplating on a substrate; (b) a step of contacting the contact portion and the above substrate by an organic insulating material layer serving as a holder; over-electricity (c A step of forming a recessed portion on the organic insulating material layer from the surface side of the organic material layer to a predetermined portion of the electrical contact portion; (d) forming a conductive portion by electroplating in the recessed portion, so that the conductive portion is directly 97422.doc 12 200527997 Step of conducting connection to the electrical contact part. (E) Step of removing the substrate. In the present invention, through the above-mentioned steps, the electrical contact junction of the part, the holder, and the conducting part; the number of manufacturing steps for the sexual contact is small; Instead of the necessary abutment in the electrical contact with the structural body, a retaining body composed of a 佯 捭 r ... mechanical insulating material layer is provided instead. As shown in the above step (d) and step (d), it is possible to form a recessed portion and a conductive portion in the holding body, thereby reducing the cost. ~ First-comparable production can be achieved. In addition, in the step (b) of the above-mentioned steps, a holder formed of an organic insulating material layer is formed on the substrate and the electrical contact portion at the substrate = stage. Therefore, instead of using conventional methods such as thermocompression bonding to mount the abutment single body and the electrical contact portion removed from the substrate > fatty soil, it is easy to reduce the thickness of the holder as desired. miniaturization. In the above-mentioned process, the electrical contact portion can be directly contacted with the structure, so it is not necessary to connect and fix the two while using a conductive compound to heat and connect them as before. Various steps, and in addition, the electrical conductivity of the above-mentioned electrical contact material feeding passage is also good. In addition, in the present invention (A), it is preferable that the following step (f) is provided between the step (i) and the step (ii).偏离 At a position deviating from the conducting portion and at least opposite to the -part of the electrical contact portion in the film thickness direction ', a through hole is formed from the surface of the above-mentioned organic insulating material layer 97422.doc 200527997 to the moon to make the electrical property The step of exposing the contact hole in the through hole. 〇 Knife is above. Preferably, the following step (g) is performed between the step (i) and the step (ii). There is a method of three-dimensionally forming an electrical contact portion exposed in the through hole. In addition, in the present invention, it is preferable that the above-mentioned concrete material includes a screw contact portion with a screw == and a screw contact with the screw. "The base portion around the spiral contact portion forms the electrical contact. In the step of ⑷, the organic insulating material layer is formed from the surface side of the organic material layer to the electrical contact. In the above-mentioned step, the through-hole is formed so that a portion of the spiral contact portion constituting the electrical contact portion is exposed in the through-hole. In addition, in the present invention, it is preferred In order to use a solder resist in the organic insulating material layer used in the step (b), it is preferable that the solder resist is made of a positive resist by using a mask layer in the step (C).

Further, it is preferable to perform the exposure and development using the mask layer in the above-mentioned step and remove the solder resist of the exposed portion. Through holes are formed. As described above, by using a positive solder resist, recesses and through holes can be easily and appropriately formed on the holder. In the present invention, the solder resist described in the above 97422.doc -14-200527997 can be used. The formed organic insulating material layer remains to the end and functions as a holder. Previously, it was necessary to separately prepare a base for mounting the above-mentioned electrical contact portion, but in this hair month, it can also form a base during a series of manufacturing processes. One of the features of the present invention is the holder of the stage. In the case where the abutment is separately installed as before, there are disadvantages such as an increase in production cost and a long manufacturing process. In the present invention, a series of The process of continuously manufacturing the electrical contact holder is sufficient to manufacture the electrical contact structure in a simple manner and also simplifies the structure of the electrical contact structure. In addition, in the present invention, it is preferably ·· In the step (d) above, the conduction P is convexly formed so as to bulge the surface of the organic insulating material layer, thereby increasing the number of substrates provided on the printed wiring board. The connection area between the contact portion and the conductive portion, and the conductive portion protrudes toward the connected portion. Therefore, when the conductive portion is opposed to the connected portion, the back surface of the holder and the connected portion It is easy to form a space between them, and the space can be provided as a space portion for welding. 'The conductive portion and the connected portion can be easily connected and fixed by welding. The electrical contact structure of the present invention is made by electrical contact. Compared with the previous structure, the number of parts can be reduced compared with the previous one, and the electrical contact structure with a simple structure can be obtained. In particular, the previously required abutment is not required, and a holder is provided instead. In addition The conductive portion is directly conductively connected to the electrical contact portion, which can provide a structure that does not require a conductive adhesive as before and has excellent electrical conductivity. In addition, according to the manufacturing method of the present invention, Compared with before 1, the number of manufacturing steps can be reduced, and the basis σ previously required in the manufacture of the electrical contact structure is not required, and instead, it is provided by Holding the insulating material layer. According to the present invention, it is possible to simply form the recessed portion and the conductive portion 'on the holding body, and it is possible to reduce the production cost as compared with the conventional case. In the above-mentioned steps, since a holding body formed of an organic or eutectic material layer is formed on the substrate and the electrical contact portion while the substrate is still present, it is not necessary to use a method such as thermocompression bonding as before. The base contact alone and the electrical contact portion removed from the substrate can easily reduce the thickness of the holder as desired, and can achieve miniaturization of the electrical contact structure. In addition, since the conducting portion can be directly connected to the electrical contact portion, there is no need to perform the troublesome process of connecting and fixing the two while thermally star-connecting them with a conductive kiss as in the past. In addition, the electrical contact portion and The continuity between the aforementioned conducting portions is also better than before.

The surface 25b of the holder 25 is formed with a low surface 25b 1 around the through hole 25a, and is opened in a direction away from the through hole 25a. The lower surface 25b is formed to be one level higher than the outer edge of the low surface 25bl. Surface 25b2. The base portion 26b is formed in a cutout portion between the high surface 25b2 and the low surface 25bl. The surface 26bl of the base portion 26b is on the same plane as the high surface 25b2. No other materials such as conductive adhesive 97422.doc -18- 200527997 are interposed between the base portion 26b and the holder 25, and the base portion 26b and the holder 25 are directly connected to each other, as explained by a manufacturing method described later. Generally, the holder 25 is made of an organic insulating material. First, the holder 25 is coated so as to cover the spiral contact%. The base 2 讣 of the spiral contact 26 and the holder h are anchored by an anchoring effect. Wait for the connection to be fixed. As shown in FIG. 5, a recess 27 is formed in the holder 25 from the base portion 2b to the lunar surface 25c. The conductive portion 28 is formed in the recessed portion 27 by, for example, plating. The recessed portion 27 is formed to surround the through hole 25a at a position more outward than the through hole 25a # formed in the holder 25. As shown in FIG. 4, a conductive portion 28 formed in the recessed portion 27, The rear surface 25c of the holder 25 is exposed, and has a substantially circular band shape that surrounds a peripheral portion of the through hole 25a. The conducting portion 28 is formed in the holding body 25 and does not exit from other positions of the holding body 25 except that it is exposed from the moon surface 25c of the holding body 25. That is, the conductive portion 28 is not exposed in the through hole ha. The conductive portion 28 may be formed so as to be exposed to the through-hole 2. However, if the conductive portion 28 is formed in this way, the electrical characteristics may be deteriorated. Therefore, it is preferable not to expose the conductive portion 28 to the through-hole. within ha. Therefore, in the present invention, in order to form the conductive portion 28 on the holder 25, the recessed portion 27 on which the conductive portion 28 is formed is provided at a position * outside of the through hole 25a. As shown in FIG. 5, the recessed portion 27 is formed in a linear shape from the surface of the spiral contact% base portion 97222.doc -19- 200527997 below 26b2 to the back surface 25c of the holder 25, but may be formed in a shape other than a linear shape. shape. However, a straight shape is the easiest to form, and the conductivity between the base portion 26b and the conducting portion 28 is also good, so it is preferable. As shown in FIG. 5, the conducting portion 28 has a protruding portion 28 a protruding from the back surface 25 c of the holder 25, and the protruding portion 28 a is formed with a width dimension wider than a width dimension of the conducting portion 28 formed in the recessed portion 27. . The protruding portion 28a is formed by forming a protruding portion when the conductive portion 28 is electroplated, and the surface 2 8 a 1 of the protruding portion 2 8 a is formed in a convex curved shape. By forming the protrusions 28a by forming the protrusions in this manner, it is possible to increase the conductive contact with the opposite electrode 31 (the connected portion) provided on the printed wiring board 30 on the lower side of the electrical contact structure 24. Area, and when the opposing electrode 31 and the protruding portion 28 a are matched, a space portion 32 is formed between the holding body 25 and the opposing electrode 31. Therefore, the space portion 32 can be used to connect the opposing electrode 31 by a solder 33. It is used as a solder forming portion when it is in contact with the protruding portion 28a, and it is possible to appropriately weld between the opposing electrode 3 ^ and the dog-out portion 2 8 a, and it is possible to ensure a good relationship between the opposing electrode 31 and the conducting portion 28. Continuity. In addition, in the present invention, since the moon dagger is sufficiently connected between the counter electrode 31 and the protruding portion 28a, the thermal compression bonding process and the like when using a conductive adhesive as before are unnecessary, and it is simple and reliable. Groundingly connects the above-mentioned opposing electrode 3 丨 with the above-mentioned protruding portion 28 &. The material and the like of each part will be described. The spiral contact 26 is formed by electroplating or copper 4 or the like, but forming the electroplating can finely process the spiral contact 97422.doc -20- 200527997, so the car is excellent. The spiral contact 26 formed by forming the electroplated layer is preferably a layered structure, which is, for example, a layered structure in the order of Au / Ni / Au from the bottom. 4 The holder 25 is preferably formed of an organic insulating material. By forming the holding body 25 from an organic material, the material can be formed in the holding body 25 appropriately and easily without damaging the spiral contact 26 and the through hole 25a, and the accuracy can be improved. The recessed portion 27 and the through hole 25a are formed on the ground. ^ In particular, it is preferable that the holding body 25 is formed using a solder resist. As described later in the mounting method, the holding body h formed of the solder resist is exposed, This allows easy and accurate formation of the recesses 27 and penetrations Ua. The conductive portions 28 are preferably formed by electroplating. The conductive portions 28 are preferably made of Cu, Au, platinum group elements, and other materials having excellent conductivity. Metallic material In the present invention, the conductive portion 28 is formed by electroplating, and the conductive portion 28 can be electroplated under the base portion 2 6 b of the same metal spiral contact 26, and the conductive portion 28 and the conductive portion 28 can be electroplated. There is no conductive adhesive or the like between the base portions, and the two are appropriately and reliably connected to each other. The soldering 33 is, for example, paste soldering. On the electrical contact structure formed as described above, from FIG. 5 β head direction When the electronic component 25 is placed and the locking portion 26 of the cover 22 shown in FIG. 1 is locked to the locked portion 24 of the seat 21, the electronic component is pressed downward by the pressing portion 22a as shown above. The contact 35 of the odd surface of the electronic component 25 pushes each of the spiral contacts in the direction of the through hole 25a formed in the holder 25 (below), and the shape of the spiral contact 26 is expanded and deformed. The outer surface of the above-mentioned contact 35 is rolled like 97422.doc 21 200527997, and the contacts 35 and the spiral contacts 26 are electrically connected well. Fig. 6 shows the connection of the electrical contact structure 41 of the present invention. An exploded perspective view of the device 45. The electrical contact structure 41 has a plurality of spiral contacts 43 and a holder 44 as shown in FIG. 6, and specific internal structures and the like are shown in FIGS. 2 to 5. The electrical contact structure 41 is housed in a cutout W 40a formed in the base 40, and the conductive portion (the same structure as the conductive portion 28 shown in FIG. 2) of the electrical contact structure 4 is welded. The connection is fixed to the connection provided on the surface of the cutout portion_40a The symbol 46 is a printed wiring board 46, and a plurality of electrode portions (not shown) are provided on the back of the printed wiring board. A cover 42 made of resin or the like is provided on the printed wiring board 牝. The cover 42 is fitted into the cutout portion 40a of the base 40. When the cover 42 is fitted into the cutout portion ⑽ of the base 43, the spiral contacts 43 of the electrical contact structure 41 and The electrode portions of the printed wiring board 46 are electrically connected. The connector 45 shown in FIG. 6 can be installed in electronic devices such as mobile phones. The following describes the characteristic parts of the electrical contact structure 24 of the present invention. In the stand-up earth month, the electrical contact structure 24 has the p-shaped spiral contact 26 as an electrical contact, the holding body 25 and the conducting portion 28, and can basically be composed of only $. ^ Parts. Therefore, 'the number of v'pieces can be reduced compared to the previous electrical contact structure', which is enough to manufacture the electrical contact structure M of a simple structure. 97422.doc • 22- 200527997 In the present invention, the spiral contact 26 can be directly mounted on the holding body 25. In addition, the conductive portion 28 is formed on the recessed portion 27 formed on the holding body 25 by plating or the like. Instead, the conducting portion 28 can be directly connected to the spiral contact 26. Previously, the conductive screw compound was used to hold the snail contact 26 on a separately purchased abutment to make it conductively connect with the conducting portion provided on the abutment. However, in the above case, hot pressing is required. In some cases, good continuity cannot be obtained depending on the mounting accuracy. In the present invention, the spiral contact 26 can be directly mounted on the holding body 25 without using a conductive drill-in. Continuity connection, simple installation and good continuity. Further, in the present invention, in particular, forming the holder 25 from an organic insulating material or the like does not damage the spiral contact%, and it is possible to easily and accurately form the recess 27 and the through hole 25a on the holder. In the present invention, the conductive portion 28 is formed in the recessed portion 27 by a method such as plating, but the through-holes 25a and the recessed portion 27 are formed separately. A conductive portion is formed on the inner surface of the through hole. In the previous internal structure of the abutment, the necessity of ensuring the film thickness of the conductive portion of a predetermined size and the like was stated. 'The through hole of the abutment must not be too small, and Shita cannot promote the miniaturization of the entire electrical contact structure. In the present invention, in addition to the recessed portion 27 for forming the conductive portion 28, a through hole 25a is additionally formed. 'Because the holder 25 is formed of a material that is easy to be precisely processed, such as an organic insulating material, the screw contact can be matched. It is a structure that can form a minute through-hole 2 in the holder 25 to promote the miniaturization of the electrical contact structure 25 as compared with the conventional method. 97422.doc 200527997 In addition, in this month, the conductive portion 28 may be formed in a convex shape protruding from the back surface of the holder to the conductive electrode 28 and the opposite electrode 33 on the printed wiring board 30. It is sufficient to connect the fixed moon dagger with the Huixi post and fix the electrical contact structure M and the printed wiring board 30 mentioned above. 7 to 16 are process diagrams showing a method of manufacturing the electrical contact structure 24 of the present invention. Each process drawing is a partial cross-sectional view of the electrical contact structure 24 in the manufacturing process cut from the film thickness direction. Reference numeral 50 shown in FIG. 7 is, for example, a Cu substrate. A dry film resist is pasted on the above-mentioned Cu substrate 50, or a resist layer 51 is formed by applying a liquid resist by a spin coating method or the like, and then exposed and developed on the resist layer 51 to form a resist layer 51. The hollow pattern 5 1 a having the same shape as the spiral contact 26. Next, in the step shown in FIG. 8, the spiral contact 26 is electroplated in the hollow pattern 51a, and as shown in FIG. 9, the resist layer 51 is removed by dissolving with a domain solution or the like. In Fig. 9, only the spiral contacts 26 plated on the above-mentioned substrate 50 are left. In the process of FIG. Ο, the above (: 11 substrate 50 and the spiral contact 26 are covered with an organic insulating material, and the organic insulating material is formed on the above Cu substrate 50 and the spiral contact 26. Layer 52. It is preferable that the above-mentioned organic insulating material uses a solder resist. By using the above-mentioned too-drying resist, the formation of the recesses 54 and the through-holes 61 in the subsequent steps can be easily and accurately performed. The above-mentioned solder resist is positive. That is, a resist that is partially irradiated with light is used. This is because the formation of the recessed portions 5 4 and the formation of the through-holes 61 by the exposure and development process are used, 97422.doc -24- 200527997 By using a positive solder resist, these two formation steps can be appropriately performed. In addition, the organic insulating material layer 52 described above remains as the holder 25 until the last layer. Next, as shown in FIG. 11 In the process, a mask layer 53 is disposed above the organic insulating material layer 52. A hollow pattern 53a is formed on the mask layer 53. The hollow pattern 53a is located just above the base 26b of the spiral contact 26. For example, on The base portion 26b is formed in a circular fringe shape around the spiral contact portion 26a of the spiral contact 26 (see FIG. 3). Therefore, it is preferable that the hollow pattern 53a is also along the above-mentioned The form of a circular rim shape above the base 26b. The second pattern 53a is exposed to light and exposed to the organic insulating material layer 52 at a position opposite to the above-mentioned hollow pattern 532 in the film thickness direction. The organic insulating material layer 52 is formed from the surface 52a of the organic insulating material layer 52 to the base of the spiral contact 26. The recessed portion 54 on the ridge is formed vertically from the surface 52a of the organic insulating material layer 52. On the base portion 261) of the spiral contact 26, when viewed from directly above, the recessed portion 26b is in the form of a substantially circular band shape along the base portion 26b. The formation position of the recessed portion 54 can be determined arbitrarily, but it is preferably formed on the end of the electrical contact portion such as the spiral contactor 26. The “contact angle” other than the above-mentioned end portion is exposed in the through-hole 61 formed in a later step, and is pressed while being electrically connected to the contact 35 of the electronic component 29 to be elastically deformed into the through-hole 61. Therefore, it is preferable that the recessed portion 54 is formed as far as possible at the end portion of the electrical contact portion. In the case of the spiral contact 26, a portion of the spiral contact portion 26a becomes a through hole 61. The recessed portion 54 is exposed inside and is elastically deformable. Therefore, the recessed portion 54 is provided on the base portion 26b. In the step shown in FIG. 12, a conductive portion 55 is formed by plating in the recessed portion 54. The base portion is exposed in the recessed portion 54 26b, since the base portion 26b made of metal functions as an electrode during electrolytic plating, the conducting portion 55 is appropriately electroplated and grown on the base portion 26b. In the present invention, as shown in FIG. 12, it is not limited to the above. The conductive portion 55 is formed in the recessed portion $ 4, and is continuously plated with the conductive portion 55 formed in the recessed portion 54 (so-called bump formation) to protrude from the surface 52a of the organic insulating material layer 52. The protruding portion 55a. The protruding portion 55a is formed not only on the recessed portion 54 but also on the surface 52a of the organic insulating material layer 52. However, 'the portion extending to the surface 52a of the organic insulating material layer 52' is An insulating layer is grown by passivation plating. As shown in FIG. 13, the surface of the protruding portion 55a is formed with a convex curved surface. In this way, the conductive portion 55 is formed to protrude from the surface 52a of the organic insulating material layer 52. In the step of FIG. 14, the mask layer 60 and the above-mentioned organic layer are effectively made to function as a mounting surface with a counter electrode provided on a printed wiring board. The upper side of the insulating material layer 52 is opposed to each other. A hollow pattern 60a is formed on the mask layer 60, and the planar shape of the hollow pattern 60a is, for example, the same as the through hole 25a formed in the holder 25 shown in FIG. Here, the above-mentioned hollow pattern 60a is formed at a position corresponding to the spiral contact portion in the spiral contact 26. The portion 97422.doc -26- 200527997 is located opposite to the film thickness direction. In other words, the hollowed-out pattern 60a is located more inward than the recessed portion 54 formed on the organic insulating material layer 52. The hollowed-out pattern 60a does not face the recessed portion 54 in the film thickness direction. The organic insulating material layer 52 at a position opposite to the hollow pattern 60a is removed by exposure and development in the next step. If the concave portion 54 is present at a position opposite to the hollow pattern 60a in the film thickness direction, The through-holes formed in the subsequent steps expose the conductive portions 55 that are plated in the recessed portions 54. Therefore, the hollowed-out pattern 60a is positioned in the recessed portions 54 formed on the organic insulating material layer 52. Closer to the inside. In the step of Fig. 14, light is irradiated from the hollow pattern 60a toward the organic insulating material layer 52. As described above, the organic insulating material layer 52 is formed of a positive solder resist. In the step of FIG. 丨, in order to form the recessed portion 54 in the organic insulating material layer 52, the organic insulating material layer 52 is irradiated with light only at the position where the recessed portion 54 is to be formed by the mask layer 53. Therefore, at the time of the step of FIG. 14, light irradiation is not performed on the remaining organic insulating material layer 52. Therefore, in the step of FIG. 14, the organic insulating material layer 52 at the position where the through hole 61 is to be formed is partially irradiated with light by the mask layer 60, and the exposure and development can be performed appropriately. In the case of a negative resist, the place where light is not irradiated is removed. However, when the organic insulating material layer 52 is formed using the negative resist, all of the remaining organic insulating material layer 52 at the time of FIG. 14 is irradiated with light. part. Therefore, a problem arises that the through-hole 61 cannot be properly formed. Therefore, in the organic insulating material layer 52, recesses are formed by respective processes. 97422.doc -27-200527997 Four-person through-hole 61 4 is preferably a positive solder resist on the organic insulating material layer. As shown in FIG. 15, the organic insulating material layer at a position opposite to the hollow pattern 60 a of the mask layer 60 in the film thickness direction is exposed and developed by using the mask layer 60 to form the layer shown in FIG. 5. Through hole 6. As shown in Figure 5, the through hole 61 is formed from the surface 52 & to the back surface 52c of the organic insulating material layer 52, and the spiral contact portion 26 of the spiral contact 26 is from the through hole 61. Then, in the step shown in FIG. 16, the through-hole 61 of the electrical contact structure obtained through the step up to FIG. 15 is used to abut the protruding adjustment member 62 from the lower side of the through-hole 61 and point in the direction of the arrow. The protrusion-adjusting member 62 is pushed up to three-dimensionally shape the spiral-shaped contact portion exposed in the through-hole 61 upward into a spiral shape. As a result, the contact portion 26a can be three-dimensionally formed as shown in FIG. 5. In the step of FIG. 16, the electrical contact structure in the step of FIG. 15 is turned over so that the contact portion 26 a is located on the upper side of the holding body 52 and the protruding portion 55 a of the conducting portion 55 is located on the lower side. Through hole 61 Push up the protrusion adjustment part 62, but keep the dog trimming part 62 under the through hole 61 while keeping the state of FIG. 15 and push up the protrusion adjustment part 62 to form the three-dimensional shape in the through hole 61. Of course, it is also possible to enter the contact portion 26a. In the electrical contact structure formed by using each of the steps shown in FIGS. 7 to 16, basically, the holding portion is composed of only the spiral contact 26 and the organic insulating material layer 52. The body and the conductive portion 55 are formed. In this way, a series of steps can be used to form 97422.doc -28-200527997. The electrical contact structure has a very simple structure. By the side; especially when a separate abutment is purchased, the frame is connected. The steps of contacting each of the spiral contact with the vine, and the > and so on to prevent the plurality of spiral contacts from being dispersed separately (the process of attaching the spiral contact to the abutment on the abutment (^ Figure 19D) '' However, the present invention does not require such a process and realizes the realization of an intermediate manufacturing process. In particular, it does not require a conventional abutment. The abutment is formed by complicated processing. The price is high, but according to the present invention, it is very simple. In a series of manufacturing processes, an organic insulation holding a plurality of spiral contacts 26 is formed: a material layer of 52 $ can be used as the holding body of the above-mentioned organic insulating material layer μ. Therefore, compared with the previous, the holding The manufacturing process of the body molding is easy, and the production cost can be reduced. In particular, the recessed portion 54 and the through hole 61 can be easily and accurately formed at any position of the holding body, and the organic insulating material layer 52 can be formed in the formation. On the above-mentioned spiral substrate 5 (), it is expected that the abutment and the spiral contact 26 may be formed in the respective steps as before, and the two parts may be dry-attached in the subsequent steps. As a result, it can be further advanced than before. In order to reduce the size of the electrical contact structure, it is possible to form minute through-holes 61 in the holder 54 and form a film thickness that is arbitrarily thinner in accordance with the shape of the spiral contact%. In addition, in the present invention, a solder resist or the like is used as the organic insulating material layer 52 constituting the holder, and the spiral contact 26 can be directly mounted on the organic insulating material layer 52 during the formation of the solder resist. In addition, a recessed portion 54 is formed on the organic insulating material layer 52, and a conductive portion 55 is formed by electroplating therein, so that the base 2 of the spiral contact 26 is directly connected to the conductive portion 55 of the aforementioned 97422.doc -29-200527997, etc. Therefore, the previously required installation process using a conductive adhesive is not required, the installation process can be simplified, and the heat-repeated connection process necessary for the Ricoh electrical & mixture is not required, which is in contrast to the first rigid phase. It is possible to improve the conductivity between the conductive portion 55 and the spiral contact 26. In addition, in the present invention, as the organic insulating material layer 52, an example of a solder resist is given. However, the organic insulating material layer 52 may be formed of a resin such as polyimide. In the above case, it is preferable to form the recessed portion 54 and the through hole 61 by a method such as laser processing. In addition, in the present invention, as shown in the step of FIG. 16, the contact portion 26 a of the spiral contact 26 can be three-dimensionally formed using the through-hole 61 formed in the organic insulating material layer 52. In addition, as shown in FIG. 16, When the protruding portion 55a of the conductive portion 55 is conductively connected to the opposite electrode of the printed wiring board provided on the lower side of the electrical contact structure, since the space portion 32 is formed between the two components as shown in FIG. 5, This space portion can be used to "weld-join" the protruding portion 55a and the opposing electrode 31. In particular, the protruding portion 55 & is formed as a protrusion and communicates with the opposing electrode 31, so that the protruding portion can be simply and reliably welded. 55a and upper = pair; between pole 31. In addition, in each of the steps shown in FIG. 7 to FIG., The spiral contact 26 is exemplified as the electrical contact portion, but the electrical contact portion may be other than a spiral shape.
