The term "fiber set 3" as used herein refers to the concept of a fiber network before the non-woven fabric obtained by a carding machine, in addition to the non-woven fabrics of various manufacturing methods. Then, the upper layer 21 and the lower layer 22 are stacked on top of each other to form the fiber assembly for forming the upper layer 2 and the fiber assembly for forming the lower layer 22, and a thermal relief, super Relief processing such as sonic relief is integrated in the thickness direction. The sheet compression portion 23 is a compression portion formed by the relief processing, and the skin-side surface and the absorber-side surface are integrally compressed, and the thickness is smaller than that of the surface sheet 2. In the sheet compression section 23, the constituent fibers of the upper layer, the constituent fibers of the upper layer, the constituent fibers of the lower layer, and the constituent fibers of the lower layer are thermally fused with each other by the heat applied during the relief processing. Fig. 4 (a) is a view showing an arrangement pattern of the sheet compression section 23 of this embodiment. Each of the sheet compression portions 23 of this embodiment is circular, and is dispersedly arranged in a plurality of scattered dots. Each of the sheet compression portions 23 is surrounded by six other sheet compression portions 23 which have the same distance from the compression portion 23. The six sheet compression portions 23 are arranged so as to form a regular hexagon. The surface sheet 2 includes a plurality of lower layer compression portions 24 formed by compressing only the lower layer 22. The lower compression part 24 is to stack the fiber assembly for forming the upper layer 21 and the fiber assembly for forming the lower layer 22, and only apply the heat relief and ultrasonic waves in a specific pattern to the fiber assembly forming the lower layer 22. It is formed by embossing such as embossing. 96178.doc -11-1238711 In the lower compression part 24, the constituent fibers of the lower layer are fused with each other by the heat applied during the relief processing. In the lower layer, the compression portion M of the lower layer has a smaller thickness than the other portions that are not compressed. Fig. 4 (b) is a diagram showing the arrangement pattern of the lower compression section 24 in this embodiment, and is the same scale diagram as Fig. 4 (a). In the present embodiment, the lower-layer constriction portions 24 are circular, and are dispersedly arranged in a plurality of scattered points. Each lower layer is compressed so as to be surrounded by six lower-layer compression portions 24 each having an equal distance from the compression portion 24. The six The lower compression part 24 is arranged so as to form a regular hexagon. In addition, the lower compression part is located between the sheet compression parts. Except that there are one or more lower compression parts on a straight line connecting two adjacent sheet compression parts to each other, it is formed in three or more sheet compression parts. In the area of polygons (polygons in which the compressed portions of the corner sheets exist), one or more lower compression portions must be included. In this embodiment, a plurality of (about 3 to 6) lower compression portions 24 exist in a triangle-shaped area formed by the three sheet compression portions. The minimum density π of the surface sheet 2 in this embodiment is located in the portion other than the sheet compression portion 23 and the lower compression portion 24 of the lower layer 22, that is, the substantially uncompressed portion (hereinafter referred to as the lower uncompressed portion) 29. The portion 21 other than the sheet compression portion 23 (hereinafter referred to as the sheet non-compression portion) 28 has a minimum looseness and a degree W or more. From the viewpoint of improving the transferability of the liquid, especially the liquid in the thickness direction, the minimum density β of the lower non-compressed portion 29 is higher and better than the minimum density of the thin non-compressed portion 28. The ratio of the minimum density ( p2 / pi) is particularly good at 1.1-10. The minimum density of the lower non-compressed portion 29 is preferably 96l78.doc -12-1238711 0.01-0.2 g / cm3, and the minimum density pi of the sheet non-compressed portion 28 is preferably 0.001-0 · 1 g / cm3. Here, the minimum densities pi and P2 of each of the sheet uncompressed portion 28 and the lower uncompressed portion 29 can be measured as follows. Calculated from the thickness of each layer and the weight (basis weight) per unit area. The thickness of each layer is measured on the straight line passing through the two sheet compression sections 23 or the two lower compression sections 24 with a cutting machine or the like without cutting, and the thickness of the sheet non-compressed section 28 and the lower layer non-compressed section 29 is measured. thickness. The thickness measurement was performed using a KEYENCE digital HF microscope (type VH8000) to measure the thickness of the maximum thickness portion of the thin uncompressed portion 28 in the upper layer and the uncompressed portion 29 in the lower layer. The weight (basis weight) per unit area of each layer is measured separately from the upper and lower layers. The density is calculated by the following formula. Density p = basis weight / thickness. From the viewpoint of increasing the apparent density of the lower non-compressed portion 29 and improving the liquid transferability from the upper layer 21 to the lower layer 22, the arrangement pitch P2 of the lower compression portion 24 [see FIG. 4 ( b)] is smaller than the arrangement pitch P1 of the sheet compression portion 23 [refer to FIG. 4 (a)], and the ratio (P2 / pi) of the arrangement pitch is better. In the case where the arrangement distance between the sheet compression portion 23 and the lower compression portion 24 is mostly dispersed in the point-shaped compression portion, it is the distance between the individual center points of the two closest compression portions, in a curved or linear compression portion. In the case of being arranged in a plurality of parallel shapes, it is the shortest distance between the individual central lines (lines of bisected width) of two adjacent compression portions. In addition, in most cases where the dot-shaped compression portions 23 and 24 are dispersedly arranged, the shape of each compression portion may be an oval, a triangle, a quadrangle, 96178.doc -13-1238711, or any other shape other than a circle. shape. The two compression portions 23 and 24 are preferably discontinuous dots in both the longitudinal direction and the width direction of the surface sheet, but are preferably continuous in the longitudinal direction or the width direction of the surface sheet. The dot-shaped compression portions 23 and 24 are preferably uniformly dispersed throughout the entire two-layer structure portion 20 of the sheet. From the viewpoint of increasing the apparent density of the lower non-compressed portion 29 and improving the liquid transferability from the upper layer 21 to the lower layer 22, compared with the sheet compression portion 23 and the lower compression portion 24, the number of the same area of the surface sheet 2 And / or it is better that the total area is larger, and the ratio (the former / the latter) of the aforementioned number of the sheet compression sections 23 and the aforementioned number of the lower compression sections 24 (the former / the latter) is more preferably 1 / 4_1 / 5〇 A ratio (the former / the latter) of the aforementioned total area of the lower layer and the aforementioned total area of the lower compression portion 24 (the former / the latter) is more preferably 1 / 2-1 / 800. In addition, from the viewpoint of feel, skin contact, and liquid transferability, the number of sheets of 100 mm 2 per surface of the sheet compression part 23 is preferably 丨 -⑽, and the total area of the sheet compression part 23 per area is oi-35. mm2 is better. From the viewpoint of liquid transferability, it is preferable that the number of 100 mm 2 sheets on each surface of the lower compression part 24 is 4 to 35, and the total area of the lower compression part 24 per area is preferably 5 to 80 mm 2. . The number, total area, and ratio of these are measured every 100 mm2, and the measurement area is performed at a place where the thin-sheet compression portion 23 and the lower-layer compression portion 24 are formed in a uniform pattern. The overlapping portion formed when the compression portion and the sheet compression portion 23 of the fiber assembly for forming the lower layer overlap is not included in the number of the lower compression portions 24 or the area when the total area is calculated. From the viewpoint of improving the transferability of the liquid in the thickness direction, the surface sheet 2 preferably has a gradually or stepwise reduction in the fiber diameter of the constituent fibers from the surface facing the absorber side on the skin side. As a specific form in which the fiber diameter of the constituent fibers is gradually reduced, there may be mentioned a form in which the fiber diameter of the fibers constituting the upper layer 21 is smaller, and the fiber diameter of the fibers constituting the lower layer 22 is smaller. The average fiber diameter of the fibers of the upper layer 21, the form in which the average fiber diameter of the fibers of the lower layer 22 is small, and the like. In the case where fibers of different fiber diameters are mixed in any one of the upper layer 21 and the lower layer 22, or each of the two layers, the average fiber diameter of the upper layer 21 or the lower layer 22 can be obtained from the weight ratio of the fibers constituting the upper layer or the lower layer. For example, when the upper layer is composed of 75% by weight of fibers having a fiber diameter of 3dtex and 25% by weight of 4dtex fibers //, the average fiber diameter of the upper layer is 3 25dtex (= 3dtexx 0.75 + 4dtexx 0.25). The specific effect of the successive decrease in the fiber diameter can be listed in the fiber assembly constituting the upper layer 21 and / or the fiber assembly b constituting the lower layer 22, from the skin side to the absorber side, and the fiber having a smaller fiber diameter The shape of the diameter slope. Examples of the fibers constituting the upper and lower layers include pulp fibers, hydrophilic fibers such as rayon, cotton, cellulose acetate, polyolefin fibers such as polyethylene and polypropylene, and polyethylene terephthalate. Condensed fibers such as polyester and polyamide, fibers of vinyl monomer polymers such as polyethylene gas and polyvinyl acetate, and the like. These may be single-component composite fibers, or may be composite fibers composed of a plurality of components in a side-by-side type or a core-sheath shape. Hydrophobic synthetic fibers are preferably hydrophilized with a hydrophilic oil. Further, from the viewpoint of the processability of the lower layer of the surface sheet 96178.doc -15-1238711 of this embodiment at the time of high-speed production, heat-shrinkable fibers, particularly those without latent crimpability fibers, are preferred. The heat-shrinkable fiber system is made of a thermoplastic polymer material and has heat shrinkability. The latently shrinkable fiber system can be heated in the same way as the conventional non-woven fiber before heating, and by adding a special temperature, A fiber having the properties of helical curling and shrinking. From the viewpoint that the sheet compression part 23 and / or the lower compression part 24 are thermally embossed, ultrasonic relief, or the like having good heat setting properties, the viewpoint of improving the bonding between the upper and lower layers of the surface sheet is improved. At least a part of the surface includes thermal & sigma fiber made of < plastics such as polyethylene propylene and the like " sigma fiber (composite fiber composed of thermoplastic resin, fiber made of thermoplastic resin as a whole, etc.), The content of the thermally fusible fiber is preferably 70-100% based on the weight of each of the upper and lower layers. The surface sheet 2 of this embodiment is formed by embossing to form the fiber assembly of the lower layer 22, and forming the lower compression portion 24, and then the fiber assembly of the upper layer 21 is laminated thereon. It is obtained by integrally applying relief processing. In addition, as a method for forming the sheet compression portion 23 and the lower compression portion 24, an adhesive or the like may be used instead of relief processing.隹 2 The fiber assembly forming the lower layer 22 and the fiber for forming the upper layer 21 are formed. Although the mouth body 5 is an unrestricted breathable non-woven fabric, a hot-rolled non-woven fabric, a spun non-woven fabric, and a cloth, it is made of uncompressed material. From the viewpoints of bulkiness and high density of fibers in the vicinity of the compressed portion, a breathable nonwoven fabric is preferred. According to the surface sheet 2 of this embodiment, in the sheet non-compressed portion 96l78.doc -16-1238711 28 of the upper layer 21, in order to form a horizontally dense gradient of the fiber density as it approaches the sheet compressed portion 23, as in As shown in FIG. 5, the liquid a on the skin side of the surface sheet 2 is discharged (supplied), as shown by the arrow a 1, and diffuses in the sheet non-compressed part 28 of the upper layer 21 against the sheet compression part 23 and is compressed by the sheet. The vicinity of the part 23 is smoothly transferred to the absorber side via the lower layer 22. At the same time, even if the liquid A is not diffused (separated) from the supplied part to a horizontal position, as shown by the arrow A2, the thick gradient between the thin non-compressed portion 28 and the lower non-compressed portion 29 is used. , From the upper layer 21 to the lower layer 22, and then by forming the lower layer compression portion 24, a horizontally dense gradient in the lower layer 22 is generated, in the boundary portion of the upper layer 21 and the lower layer 22 or in the lower non-compressed portion 29 of the lower layer 22. The diffusion is smoothly transferred from the vicinity of the compression section 24 located below the lower layer 22 to the absorber side. In this way, the liquid discharged (supplied) on the surface sheet 2 does not remain on the surface of the surface sheet, but is quickly transferred to the absorbent body. Therefore, it can effectively prevent unpleasant or sweltering caused by the liquid remaining on the surface layer of the surface sheet, and leakage due to the liquid flowing through the surface. Furthermore, the liquid having a color such as menstrual blood can be absorbed, and the color can be made inconspicuous. The effect of concealment is good. From the viewpoint of the workability and feel of the surface sheet of the present invention, the basis weight of the two-layer structure portion 20 in which the upper layer 2 i and the lower layer 22 are laminated is 20-70 g / m2, which is particularly preferably 30-60 g / m2. . The sanitary napkin shown in Figs. 6 and 7 is an embodiment of the absorbent article according to the fifth and sixth inventions, and includes a surface sheet 2 A, a liquid-impermeable back sheet 3, and the two. The liquid-retaining absorbent body 4 'between the sheets is lengthwise in texture. The surface sheet 2 A is an embodiment (also referred to as a second embodiment) of the surface sheet of the absorbent article 96178.doc 17 1238711 of the fourth invention. As shown in FIGS. 6 to 8, the surface sheet 2A according to the second embodiment is also the same as the surface sheet 2 described above, and includes a laminated nonwoven fabric having an upper layer 21 disposed on the skin side and a lower layer 22 disposed on the absorber side. Both sides in the longitudinal direction have a single-layer portion 25 composed of only the upper layer 21. The surface sheet 2A is disposed on a sanitary napkin 1a in the same manner as the surface sheet 2 described above. Regarding the sanitary napkin 1A and the surface sheet 2A of the second embodiment, the points that are different from the aforementioned sanitary napkin 1 and the surface sheet 2 are mainly described about the same points, and the same symbols are omitted and the description is omitted. . Regarding the sanitary napkin 1A and the surface sheet 2A according to the second embodiment, the points that are not particularly described are applied to the extent that the descriptions of the front sanitary napkin and the surface sheet 2 are not inconsistent. The surface sheet 2A of the second embodiment, as shown in FIGS. 8, 9 (a), and 9 (b), has a large number of sheet compression portions 23, and the upper layer 21 and the lower layer 22 are integrally compressed in the thickness direction and formed. The lower compression portion 24 is formed between the sheet compression portions 23 and 23 and compresses only the lower layer 22. The sheet compression part 23 of the second embodiment is laminated on top of each other to form the fiber assembly of the upper layer 21 and the fiber assembly of the lower layer 22, and the layered carcass is processed by applying a protrusion for heating and opening. Holes. A hole is processed by a hole-forming protrusion, and a hole-opening device is used, which includes, for example, a first roller having a large number of hole-forming needles (for example, cylindrical protrusions) formed in a specific pattern on a peripheral surface, and is relatively disposed on the first roller. A second roller having a concave portion corresponding to the number of opening needles on the peripheral surface, and a fiber assembly for forming an upper layer and a fiber assembly for forming a lower layer are inserted between the two rollers, 96178 .doc 1238711 The foregoing laminated body is performed. / Special sheet crimping part 23 is a part which is compressed by the pressing of the projection for the hole during the aforementioned hole-cutting process, and is integrated in the sheet compression part 23 of this embodiment by the heat applied during the hole-cutting process. , The fiber assembly constituting the upper layer and the fiber assembly constituting the lower layer are bonded to each other by thermal fusion. The sheet compression portion 23 has an opening 23a formed at the center of the sheet compression portion 23 so as to penetrate therethrough. The periphery of the opening 23a of the sheet compression portion 23 is compressed and compacted when the opening is processed by the projection for the opening. In the openings 23a of the second embodiment, the constituent fibers of the upper layer, the constituent fibers of the upper layer and the constituent fibers of the lower layer, and the constituent fibers of the lower layer are thermally fused with each other by the heat of the protrusions for the openings. The inner wall surface of the hole, the surface of the fiber melts and solidifies, and the permeability of the liquid of the opening 23a is increased. The capillary structure of the fiber is maintained by the compression of the thermally fused opening 23a, which improves the absorption. From the viewpoint, it is preferable that the film is not completely formed into a film in such a manner, and means such as control of opening conditions or blending of non-fusion fibers described later are used.

The hole becomes difficult to occlude, and the opening m protrudes to the extent that the opening peripheral portion 23b protrudes away from the absorption existing around it. In the case where the recess does not exist, the protruding height of the plane fairy is 96178.doc • 19-1238711 nun or more, which is 〇2-0.5 mm, particularly good according to Figure 8) At least 5-50% of the thickness is better and more ideal 20_40%. It is also a surface sheet: the thickness of the surface sheet is the thickness of the largest part of the sheet alone and in an unloaded state (without external force applied), and the aforementioned protruding height η is also measured in the same state. Moreover, when the opening peripheral edge portion 23b protrudes from the absorber side, the lower layer 22 side faces downward, and when the surface sheet is placed on the horizontal plane in a separate and unloaded state (state without external force), the front end portion of the opening peripheral edge portion 23b Those who do not reach the aforementioned level are also included. Fig. 9 (a) is an enlarged plan view showing a part of the surface on the upper layer 21 side of the surface sheet 2A, and shows the arrangement pattern of the sheet compression portion 23 having the openings 23a. The sheet compression sections 23 of the second embodiment are each circular, and are distributed in a plurality of scattered points. Each of the sheet compression sections 23 is surrounded by six other sheet compression sections 23 which have the same distance from the compression section 23, The six sheet compression portions 23 are arranged so as to form a regular hexagon. The surface sheet 2A has a plurality of lower compression portions 24 formed by compressing only the lower layer 22. The lower compression portion 24 is used for forming the fiber assembly for forming the upper layer 2 and the fiber assembly for forming the lower layer 22, and only for forming. The fiber assembly of the lower layer 22 is formed by applying relief processing such as thermal relief or ultrasonic relief in a specific pattern. In the lower compression section 24, the constituent fibers of the lower layer are thermally fused with each other by the heat applied during the relief processing. In the lower layer, the lower compression portion 24 has a smaller thickness than the other portions not compressed. FIG. 9 (b) is a plan view showing a part of the surface of the lower layer 22 side of the enlarged surface sheet 2A (the same scale as that of FIG. 9 (a)), showing the lamination of the second embodiment 96178.doc -20-1238711 part 24 Configuration pattern. The sheet compression portion 23 and / or the lower compression portion 24 are those having good heat setting properties such as thermal relief, ultrasonic relief, and heating perforation processing, so as to improve the bonding between the upper and lower layers of the surface sheet. From the viewpoint of improvement, at least part of the surface of each of the upper layer and the lower layer includes thermally fusible fibers composed of thermoplastic fibers such as polyethylene and polypropylene (composite fibers composed of a thermoplastic resin with a sheath component, and the entire thermoplastic Fibers made of resin, etc.) are preferred, and the content of the heat-fusible fibers is preferably 50-100% for the weight of each of the upper and lower layers. • In order to control the degree of solidification of the upper and lower constituent fibers, it is possible to contain fibers that are difficult to fuse (hereinafter referred to as non-fusion fibers). By including non-fusion fibers, the sheet compression portion 23 has a non-thermally fused region. The liquid entering the surface sheet passes through the sheet compression portion 23 and the liquid is introduced into the opening peripheral portion 23b, and can be easily absorbed by the absorbent body. As the non-fusion fiber, from the aforementioned heat-fusion fiber, a fiber or a composite fiber composed of a single combination containing a resin having a melting point of 25 ° C or higher can be used. As shown in FIG. 8, the surface sheet 2A of the second embodiment is adjacent to the two openings 23a and 23a, and has a convex shape on the skin side. In this way, the openings 23a and 23a have a convex shape on the skin side, thereby having good softness and touch, and the portion that contacts the skin is reduced, and the liquid easily moves to the absorbent through the surface film or through the opening. , So the sense of dryness is further improved. According to the surface sheet 2A of the second embodiment, the liquid a on the skin side of the surface sheet 2A is discharged (supplied), and as shown by the arrow A0, it flows through the surface of the surface sheet 2A through the sheet compression portion 23 through Open hole 23a, smoothly move to the absorber side 96178.doc • 21-1238711. Further, according to the surface sheet 2a of the second embodiment, in the sheet non-compressed portion 28 of the upper layer 21, a horizontally dense gradient is formed in the fiber density as the sheet compressed portion 23 approaches, and the openings 23 are formed in The sheet compression section 23 ′ therefore discharges (supplies) the liquid a on the skin side of the surface sheet 2A as shown in FIG. 10, and as shown by the arrow A1, the sheet on the upper layer 21 toward the sheet compression section 23 is not compressed. The portion 28 diffuses and smoothly moves to the absorber side. At the same time, even if the liquid A is not diffused (separated) from the supplied part to the horizontal position, as shown by the arrow A2, the dense gradient between the thin uncompressed part 28 and the lower uncompressed part 29 is shown. , From the upper layer 21 to the lower layer 22, and further, by forming the thin layer compression portion 23 and the lower layer compression portion 24, a horizontally dense gradient in the lower layer 22 is generated toward the thin film compression portion 23 and / or the lower layer. The compressed portion 24 is diffused in the lower non-compressed portion 29. Then, the liquid moving toward the sheet compression portion 23 is smoothly transferred to the absorber side, and the liquid moving toward the lower compression portion 24 is also smoothly transferred from the vicinity of the lower compression portion 24 to the absorber side. . In this way, the liquid discharged (supplied) to the surface sheet 2A does not remain on the surface of the surface sheet, but is quickly transferred to the absorbent body. Therefore, it is possible to effectively prevent unpleasant and sweltering caused by the liquid remaining on the surface layer of the surface sheet, and leakage due to the liquid flowing through the surface, and to absorb the liquid having a color such as menstrual blood, so that the color is inconspicuous The effect of concealment is good. The surface sheet of the present invention has a basis weight of 20-70 g / m2, and particularly preferably 30-60 g / m2, from the viewpoints of processability and texture. 96178.doc -22-1238711 The others (hereinafter also referred to as the third embodiment, the dagger method) related to the surface sheet of the fourth invention will be described with reference to Figs. U, 12 (a) and 12 (b). The surface sheet 2B of the ⑷, 33, and ^ -style, mainly explains that the part having the same structure as the aforementioned surface is thin, and the symbol name with the same-is slightly omitted. The point that the surface sheet 2B 'of the present embodiment is not particularly described is applicable to the range where there is no contradiction in the description of the surface sheet 2A described above. The surface sheet 2B according to the third embodiment is a sheet compression portion formed by integrally compressing the upper layer 21 and the lower layer 22, and has a sheet compression portion having openings and a sheet compression portion 23b having no openings. Moreover, between the two adjacent openings 23a, 23 &, as shown in Fig. 丨 丨, a convex shape is formed on the skin side, and the side of the absorber is also between the two adjacent openings 23a, 23a. Forms a convex shape on the skin side. In addition, the opening peripheral edge portion 23b on the absorber side of the opening 23a protrudes from the height of the surface on the side of the layer 22 below the center position P between the two adjacent openings (below in Fig. U). As described above, the surface sheet 2B of the third embodiment has a convex shape on the skin side between the skin side and the absorber side surface through the openings 23a and 23a, so that the feeling of softness and dryness is further enhanced. In this case, it is also preferable that a capillary structure formed by compression of the fiber is formed in the opening portion due to the thermal fusion hardening, and it is preferable from the viewpoint of improving the absorbency. The sheet compression section 23A in the third embodiment is the same as the sheet compression section 23 of the surface sheet 2A described above, and has an opening 23a formed at the center to penetrate the opening projection, and the periphery is surrounded by the opening projection. It is compressed and compacted during hole processing. In addition, on the inner wall surface of the opening peripheral edge portion 23b located on the absorber side, near the opening of 96178.doc -23-1238711, the constituent fibers of the upper layer, the constituent fibers of the upper layer, and the lower layer are heated by the heat of the protrusions for the openings. The constituent fibers and the constituent fibers of the lower layer are thermally fused with each other. The openings 23 of the 3 Besch method are arranged in a row of a plurality of openings arranged in series in one direction (the md direction at the time of manufacture, the up-down direction in FIG. 12 (a)) so as to be orthogonal to the one direction (CD direction at the time of manufacture) The method of generating plural rows is formed to generate a ridge between adjacent rows and rows that extends along such rows. The opening is a specific direction of the sheet (MD direction during manufacture, CD direction, tilt direction with respect to MD direction 45.) and / or adjacent openings 23a, 23a in a direction orthogonal to the whole are on the skin side. Convex-shaped openings (three-dimensional openings) are preferred. A cross section along the left-right direction (CD direction at the time of manufacturing) of FIG. 12 (a) is shown in FIG. Also, the opening 23a of the third embodiment has a larger diameter toward the recessed portion on the skin side with the opening 23a as the center than the surface sheet, and there is no opening in the recessed portion with the opening 23a as the center. The plurality of sheet compression portions 23B. The surface sheet 2B of the third embodiment is a layered fiber assembly for forming the upper layer 21 and a fiber assembly for forming the lower layer 22, which are previously compressed by a relief process such as thermal relief or ultrasonic relief. The embossing process such as thermal relief and ultrasonic relief is applied to the laminated body, and the upper layer 21 and the lower layer 22 are integrated in the thickness direction, and then the laminated nonwoven fabric is protruded with holes for application by heating. It is formed by drilling. For example, the above-mentioned boring device can be used for the boring process of the protrusion for boring. The boring process in this embodiment is made thinner than the non-boring 96178.doc -24- 1238711 pitch of the compression section 23B P3 is preferably a pattern in which the pitch P4 of the sheet compression portion 23a having openings is large [see FIG. 12 (a)]. In addition, in order to form a convex shape on the skin side between the openings 23a and 23a, it is necessary to appropriately set the diameter or interval of the opening projections used for the opening process, the straight projection of the opening projections, and the corresponding brother. The ratio of the opening diameter of the concave portion of the two rollers is equal. According to the surface sheet 2B of the third embodiment, the same effects as those of the surface sheet 2A can be obtained. In addition, the number of thin sheets of 100 mm2 per surface of the openings 23a is preferably ⑼, and the number of the compressed portions of the sheet without the openings is 50-200 of the thickness of the thin sections with the openings. % Degree is better. χ, the number per 100_2 is measured in a region having a uniform pattern and forming the sheet compression portions 23A, 23B and the lower compression portion%. As described above, the preferred embodiments of the first to sixth inventions can be appropriately modified without departing from the scope of the invention. For example, the surface sheet may include a single-layer portion 25 composed of only two upper layers at the front and rear ends in the longitudinal direction, and the surface sheet may be located in the single-layer portion 25 on each side portion of both sides in the longitudinal direction of the sanitary napkin 1 The method may be such that the longitudinal direction and the width direction of the sanitary napkin 1 are uniformly arranged. The royal body of the surface sheet may have a two-layer structure composed of an upper layer 21 and a lower layer 22. The sheet compression part 23 and the lower compression part 24 may be formed in the -v excretion part of the absorbent article ', which is not formed on the entire surface sheet or a two-layer structure part-the whole may be used. In addition, the surface sheet of the present invention may have vertical openings penetrating through the upper layer 21 and the lower layer 22, and a plurality of sheet compression portions 23 96178.doc -25-1238711 may be arranged on the inner wall surface of the three-dimensional opening. Such a sheet is thin, for example, by inserting the surface sheet 2 of the previous embodiment into a profiled roller, which is surrounded by a large number of piercing needles and rollers, which have a large number of inserted piercing needles. The holes are obtained by forming holes in the surface sheet 2. The surface sheet 2α, 2B, and the two-layer structure portion 20 of the 4th to 6th inventions may have at least eight openings. In the single-layer portion 25 composed of the upper layer 21, openings penetrating through the upper layer 21 may be formed. Formation is also possible.
