The absorbent article 1 according to the embodiment and the package 100 of the absorbent article in which the absorbent article 1 is packaged by the packaging sheet 70 will be described with reference to Figs. 1 to 7 . Fig. 1 is a plan view of a package body of an absorbent article as viewed from a skin contact surface side, and Fig. 2 is a rear view of a package body of an absorbent article. Fig. 3 is a schematic cross-sectional view showing the A-A section shown in Fig. 1. The package 100 for an absorbent article has an absorbent article 1 and a packaging sheet 70 in which the absorbent article 1 is packaged. The absorbent article 1 of the present embodiment is, for example, a sanitary napkin.

In the package 100 for an absorbent article, the packaging sheet 70 and the absorbent article 1 are folded in a state in which the absorbent article 1 is placed on the packaging sheet 70, and the absorbent article 1 is individually packaged. 1 and 2 show that the absorbent article 1 is individually formed by the packaging sheet 70. After the ground is packaged, the absorbent article 1 is opened. The state of packaging of the absorbent article 1 will be described in detail later.

The absorbent article 1 has an absorbent main body 1A having a liquid-permeable surface sheet 10 for permeating a liquid, a liquid-impermeable back sheet 20 which does not allow liquid to permeate, and an absorbent portion 1B. In the body 30, the crotch portion 1B extends outward in the width direction from the absorbent body 1A. The absorbent main body 1A is a portion in which the surface sheet 10, the back sheet 20, and the absorber 30 are laminated, and the crotch portion 1B is a portion closer to the outer side in the width direction than the absorber 30.

The absorber 30 is disposed between the surface sheet 10 (or the sheet material 80 containing the Chinese medicine material) and the back sheet 20. Therefore, the absorber 30 is indicated by a broken line in Fig. 1 . The absorber 30 is disposed in a central portion of the longitudinal direction L and the width direction W of the absorbent article 1.

The crotch portion 1B includes a flap portion 43 disposed on the outer side in the width direction of the excretory opening abutment region that abuts against the excretory opening of the wearer, and a hip portion 44 disposed closer to the rear than the flap portion 43 . Further, the absorbent article 1 includes a side sheet 41 which is provided on the outer side of the absorber 30 in the width direction W.

Further, in the absorbent article 1, the excretory opening abutting region abuts against the vaginal opening of the wearer, for example, when the absorbent article 1 is attached to the wearer's underwear, the two legs of the underwear are disposed. The area between the openings. Further, the center of the excretory opening abutment region is the center in the longitudinal direction and the width direction of the region where the wearer's excretory opening abuts. For example, in an absorbent article having a flap portion, the center of the longitudinal direction of the flap portion is a row The center of the long side direction of the vent area. Further, in the absorbent article having no flap portion, the shortest position in the width direction of the absorbent body is the center in the longitudinal direction of the drain opening abutment region.

The surface sheet 10 is a liquid permeable sheet that allows a liquid such as a body fluid to permeate. The surface sheet 10 covers at least the surfaces of the absorber 30 and the sheet 80. The surface sheet 10 is not particularly limited as long as it is a sheet-like material having a structure in which a liquid is transmitted through a nonwoven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet. For the material of woven or non-woven fabric, any material of natural fiber or chemical fiber can be used.

In order to suppress liquid transfer on the surface sheet 10, uneven processing may be applied to the surface of the surface sheet 10 on the skin contact side, or air may be contacted during formation of the surface sheet 10 formed of the non-woven fabric, thereby forming a basis weight of the nonwoven fabric. Average. Further, a second sheet for taking in body fluid from the side of the surface sheet 10 toward the side of the absorber 30 may be provided between the surface sheet 10 and the absorber 30.

The back sheet 20 has a length substantially the same as the length of the surface sheet 10. As the back sheet 20, a film mainly composed of polyethylene, polypropylene or the like, a gas permeable resin film, a sheet of a gas-permeable resin film bonded to a non-woven fabric such as a spunbond or a water needle nonwoven fabric, or the like can be used. The back sheet 20 is preferably a material having a degree of softness that does not cause a feeling of discomfort when worn. The back sheet 20 of the present embodiment is composed of a film of a liquid-impermeable polyethylene.

The absorbent body 30 contains: an absorbent sheet 31 formed of a thin fabric or a non-woven fabric; and is disposed closer to the skin than the absorbent sheet 31 On the joint side, an absorbent core 32 of pulp fibers is laminated. The absorbent core 32 has a lower absorbent core 32A that abuts against the surface of the absorbent sheet 31 on the skin contact side, and an upper absorbent core 32B that abuts on the surface closer to the skin abutting side than the lower absorbent core 32A.

The absorbent sheet may be formed of a thin fabric or a non-woven fabric. As the nonwoven fabric constituting the absorbent sheet, a nonwoven fabric formed of a thermoplastic fiber and subjected to a hydrophilic treatment or a nonwoven fabric formed of a hydrophilic fiber can be used. Further, as the nonwoven fabric constituting the absorbent sheet, an air-laid sheet in which a hydrophilic fiber or a powder is formed into a sheet shape by an air laid method can be used.

The absorbent core 32 is composed of a layer of pulp fibers. The pulp fibers of the absorbent core 32 are not covered by a thin fabric or a non-woven fabric and abut against the surface sheet 10. The absorbent core 32 functions as a laminate of the present invention.

The absorbent core 32 is smaller than the absorbent sheet 31 in the longitudinal direction L and the width direction W. Further, the upper absorbent core 32B is smaller than the lower absorbent core 32A in the longitudinal direction L and the width direction W. The upper absorbent core 32B is configured such that the basis weight of the absorbent material is higher than that of the lower absorbent core 32A, and is disposed in the central region CA including the excretion opening abutment region.

In the plan view shown in Fig. 1, the upper absorbent core 32B is provided in a region surrounded by a press portion that compresses the surface sheet 10 and the absorbent body 30 in the thickness direction. The central area CA is a region surrounded by the first press portion, which will be described later, in the plane of view.

The density of the absorbent sheet 31 is higher than that of the absorbent core 32. The absorbent sheet 31 and the absorbent core 32 are disposed in the longitudinal direction, and extend toward the outer side in the width direction from the first press portion to be described later. The body fluid that is guided to the outside in the width direction from the first press portion is diffused to the absorbent sheet having a relatively high density, and the body fluid is also transported to the lower region of the absorbent core 32. Since the absorption efficiency is improved by diffusing the body fluid, it is difficult to exceed the absorption capacity of the central region including the discharge port abutment region.

In the present embodiment, the upper absorbent core 32B and the lower absorbent core 32A are integrated. The upper absorbent core 32B and the lower absorbent core 32A may be formed separately or integrated. In the absorbent core 32 according to the present embodiment, the upper absorbent core 32B and the lower absorbent core 32A are integrally formed. When the absorbent sheet 31 and the absorbent core 32 are separately formed, they may be bonded by an adhesive such as a hot-melt adhesive.

Between the absorber 30 and the surface sheet 10, a sheet material 80 containing a Chinese medicine material is disposed. The sheet member 80 is disposed at least in the drain opening abutment region. The drain abutment area is in close proximity to the wearer's area. By providing the sheet material 80 in the central region including the excretory opening abutment region, it is easy to impart the Chinese component to the wearer. In addition, the excretory opening abutment area is the area where the body fluid is most often discharged. By providing the sheet material 80 in the central region, it is possible to reduce the odor of the body fluid by the flavor component and to improve the mounting feeling.

The sheet material 80 is in contact with the pulp fibers of the absorbent core. The sheet member 80 has a rectangular sheet shape in plan view, and has an outer end portion in the longitudinal direction and an outer end portion in the width direction, that is, four corner portions 80A, 80B, 80C, and 80D. The corners of the sheet have: front corners 80A, 80B on the front side and corners 80C, 80D on the back side. About thin The configuration of the sheet 80 will be described in detail later.

A press portion is formed around at least a portion of the sheet member 80 in plan view. The press section is formed by compressing at least the absorber 30 and the surface sheet 10 at least in the thickness direction. The press portion has a first press portion 23 disposed along the longitudinal direction of the outer side in the width direction of the sheet member 80, and a second press portion 24 disposed closer to the outer side in the longitudinal direction than the sheet member 80. The second press portion 24 is disposed closer to the inner side in the width direction than the corner portions 80A, 80B, 80C, and 80D of the sheet member 80.

Specifically, the second press portion 24 is disposed closer to the outer side in the longitudinal direction and the inner side in the width direction than the front corner portions 80A and 80B of the sheet member 80, and is disposed closer to the inner side in the longitudinal direction and the outer side in the width direction than the front corner portions 80A and 80B. The first press section 23. The first press portion 23 and the second press portion 24 are disposed apart from each other.

For example, when the first press portion 23 and the second press portion 24 are continuously annularly arranged, and the sheet member 80 is disposed inside, the corner portion of the sheet member 80 may interfere with the annular press portion, and the sheet member may not be formed. The area is fully expanded.

However, since the first press portion 23 and the second press portion 24 are disposed individually and the corner portions of the sheet material are disposed between the gaps, the first press portion 23 and the second press portion 24 are arranged in a continuous arrangement. A corner portion can be disposed between the first press portion 23 and the second press portion 24, and a wider area of the sheet material can be disposed.

Further, since the first press portion 23 and the second press portion 24 are discontinuous in segments, it is possible to suppress excessive diffusion of body fluids along the press portion. example For example, when the body fluid diffused along the first press portion is also diffused along the second press portion, the body fluid is excessively diffused in the longitudinal direction. However, the outer end portion in the longitudinal direction of the first press portion is segmented from the second press portion, and it is possible to suppress the diffusion of the body fluid from the first press portion to the second press portion.

When the wearable article 1 is in a state of being worn by the wearer, the absorbent article 1 is deformed inward in the width direction with the first press portion as a base point when pressed from the outer side in the width direction. Fig. 4 is a view schematically showing a deformed state of the absorbent article 1 in an installed state. Fig. 4 is a view showing the state in which the underpants S are attached based on the cross section shown in Fig. 3. The fourth (a) diagram is the state before the deformation, and the fourth (b) diagram is the state after the deformation.

In the state before the deformation, as shown in Fig. 4(a), the sheet member 80 of the absorbent article 1 is in a substantially smooth state and is disposed to face the discharge port of the wearer. In this state, a state in which a force is applied to the central portion in which the upper absorbent core 32B is disposed from the outer side in the width direction toward the inner side in the width direction is as shown in FIG. 4(b), and the pair of first press portions 23 are deformed inward in the width direction. .

When the absorbent article 1 is pressed inward in the width direction from the outer side in the width direction, the absorbent core 1 is pushed through the press portion to press the absorbent core closer to the inner side in the width direction than the press portion. At this time, the surface of the sheet side of the absorbent core is not provided with a thin fabric or the like, and is in contact with the pulp fibers. In addition, the pulp fibers are relatively soft and elastically deformed.

Therefore, when the absorbent article 1 is pressed inward in the width direction, the pulp fibers are easily deformed into a convex shape, and the deformation of the pulp fibers is not suppressed by the thin fabric or the like, and therefore is directly transmitted to the sheet member 80. And change In comparison with the state before the shape, the upper absorbent core 32B is close to the wearer side. Therefore, the surface sheet 10 and the sheet material 80 are disposed closer to the wearer.

Further, the second press portion extends in the width direction. When the force is applied to the inner side in the width direction from the outer side in the width direction, the second press portion can suppress the deformation in the inner side in the width direction, and the absorption core between the first press portions can be prevented from being excessively deformed into a convex shape.

Further, the press portion has a third press portion 25 that is disposed closer to the front side than the second press portion 24 located on the front side, and a fourth press portion 26 that is disposed closer to the rear side than the second press portion 24 that is located on the rear side. And a point press portion 27 disposed on the outer side in the width direction of the first press portion 23 and closer to the outer side in the longitudinal direction than the second press portion 24.

The dot press portion 27 is formed in plural at intervals. The point press portion 27 is disposed closer to the outer side in the width direction than the first press portion 23 and is not disposed closer to the inner side in the width direction than the first press portion 23 . Therefore, when the absorbent article 1 is applied with force from the outer side in the width direction toward the inner side in the width direction, the first press portion is closer to the outer side in the width direction (the area where the press portion is formed). While maintaining the smooth state, the region closer to the inner side in the width direction than the first press portion (the region where the upper absorbent core 32B is disposed) is likely to approach the wearer side.

In addition, by forming the bit-shaped press portion 27 in the region closer to the outer side in the width direction than the first press portion 23, the rigidity is increased, and the stress from the outer side in the width direction is easily transmitted to the first press portion 23. Therefore, it is disposed thinner than the first press portion 23 in the width direction inner side. The sheet 80 is easier to adhere to the wearer and can impart the ingredients of the traditional Chinese medicine material to the wearer.

In addition, the center of the first press portion 23 in the longitudinal direction is formed in a convex shape that protrudes outward in the width direction, and the length of the first press portion 23 in the width direction is the longest. Therefore, when a force is applied to the absorbent article from the outer side in the width direction toward the inner side in the width direction, the height of the deformed portion is easily secured, and the sheet member 80 is easily adhered to the body. In addition, the body fluid that has spread along the first press portion gradually moves toward the inner side in the width direction toward the outer side in the longitudinal direction. Therefore, side leakage can be suppressed.

Further, the press portion of the absorbent article may be formed by pressing at least the surface sheet 10 and the absorbent body 30 in the thickness direction T, and various configurations may be employed. For example, it may be formed by press working or embossing, and its shape may also be a lattice mesh or a honeycomb shape. Further, the first press portion 23 and the second press portion 24 of the present embodiment are constituted by a plurality of press portions that are discontinuously arranged, but may be formed continuously in a line shape.

Further, the sheet member 80 of the present embodiment has a structure that can be separated from the absorber 30. For example, when the absorbent article is used for a long period of time, the absorbent body 30 may be wrinkled by moisture or the like, and the absorbent body 30 may not be convex toward the wearer side. However, since the sheet member 80 can be separated from the absorbent body 30, even if the absorbent body 30 is creased and does not become convex, the surface sheet 10 and the sheet member 80 can be detached from the absorbent body 30, and the surface sheet 10 and The sheet material 80 is deformed toward the body side.

The surface sheet 10, the sheet member 80, the absorber 30, and the back sheet 20 can be joined in order to prevent separation between the respective layers. Such The joining can use embossing, ultrasonic, hot-melt adhesive, etc., either alone or in combination. Further, in order to prevent the absorber from being detached and wrinkled during wearing, or to adjust the thickness of the absorber, embossing may be applied to the absorber.

The side sheets 41 are disposed on both sides of the surface sheet 10. The side sheet 41 can be selected from the same material as the surface sheet 10. However, in order to prevent menstrual blood from flowing over the side sheet 41 to the outside of the absorbent article 1, it is preferred to have hydrophobicity or water repellency. Specifically, a spunbonded nonwoven fabric or an SMS nonwoven fabric or the like is used, and in particular, in order to reduce skin irritation caused by friction, a hot air non-woven fabric is preferred.

The side sheet 41 covers a part of the side edge of the absorber 30 and the crotch portion 1B. The inner end portion 41E in the width direction of the side sheet 41 is wider than the first long side crease FL1 and the second long side crease FL2, which will be described later, and the first long side crease FL1 and the second long side. The edge crease FL2 is adjacently arranged.

In the absorbent article 1, the edges of the surface sheet 10, the side sheets 41, and the back sheet 20 are joined, and the absorber 30 is sealed inside. In the joining method of the surface sheet 10 and the back sheet 20, either one of hot embossing, ultrasonic, or hot-melt adhesive, or a plurality of types may be combined.

The surface of the back sheet 20 that is in contact with the undergarment is provided with a plurality of adhesive regions coated with an adhesive. The adhesive region has a body adhesion region 51 (see FIG. 3) provided on the non-skin contact side of the absorbent body 1A, and a crotch adhesion region provided on the non-skin contact side of the crotch portion 1B. 52 (refer to Figure 3). In addition, related to this embodiment Although the partial adhesion area 52 is provided only in the flap part 43, it may be provided in the hip circumference part 44.

In the state before use, the body adhesion region 51 is covered by the body sheet 61 as a release sheet, and the crotch adhesion region 52 is covered by the crotch sheet 62 as a release sheet. The body sheet 61 and the crotch sheet 62 prevent deterioration of the use of the pre-adhesive.

The body sheet 61 is disposed between the body adhesion region 51 and the packaging sheet 70. The surface of the body sheet 61 on the side of the body adhesion region 51 is subjected to a release treatment, and is configured to be separated from the body adhesion region 51. The surface of the crotch region 52 on the side of the crotch region 52 is subjected to a release treatment, and is configured to be separable from the crotch region 52.

The body sheet 61 and the crotch sheet 62 are respectively attached to the packaging sheet 70 via an adhesive. The body sheet of the packaging sheet 70 and the side of the crotch sheet side are respectively provided with a plurality of body-attached regions 65 for adhering to the body sheet 61 with an adhesive, and an adhesive for subsequently coating the crotch sheet 62. The crotch continues to area 66.

The body following region 65 has a rib shape extending in the longitudinal direction, and has a width narrower than the body adhesion region 51, and is arranged more than the body adhesion region 51. In addition, the crotch region 66 is shorter than the crotch region 52 and more arranged than the crotch region 52.

The packaging sheet 70 is used to individually pack the absorbent article 1. The packaging sheet 70 has a facing surface 71 facing the absorbent article 1 on the back sheet 20 side of the absorbent article 1, and accommodating absorption. The state of the article 1 is located on the outer non-opposing surface 72.

Further, the packaging sheet 70 may be subjected to surface processing such as dot embossing or crepe embossing on the surface of the packaging sheet 70 for the purpose of improving texture and the like. The material of the packaging sheet 70 is, for example, a plastic film such as polyethylene, polypropylene, or polyester, or a film obtained by laminating various films such as a nylon film or a nonwoven fabric.

Since the main body sheet 61 and the crotch sheet 62 are attached to the packaging sheet 70, when the absorbent article 1 is separated from the packaging sheet 70, the packaging sheet 70 and the absorbent article 1 are separated to expose the body adhesion region 51 and the ankle adhesion region. 52.

Further, as the adhesive and the adhesive, for example, a hot melt adhesive can be used. Further, the main sheet and the crotch sheet are formed of a release-treated paper, a film, and a non-woven fabric to which peeling is applied without lowering the adhesive force of the adhesive. For example, as the body sheet 61 and the crotch sheet 62, a sheet of a silicone resin coated with a polyethylene terephthalate or a polypropylene film or a polyethylene film coated with a silicone resin may be laminated. Thin slices.

The absorbent article 1 and the packaging sheet 70 thus configured are folded at the predetermined bending position in the width direction W and the longitudinal direction L, and the surface sheet 10 of the absorbent article 1 is folded inside. In a state in which the absorbent article 1 is folded, one end portion of the packaging sheet 70 in the longitudinal direction L is attached to the packaging sheet 70. The end of the packaging sheet 70 is bonded to a portion of the packaging sheet 70 by an adhesive tape 75.

Then according to Figure 5, for the sheet containing the traditional Chinese medicine material The material 80 will be described in detail. Fig. 5 is a view showing a sheet material 80, a plan view of a fifth (a) figure, and a cross-sectional view taken along line B-B of Fig. 5(a) of Fig. 5(a). Fig. 5(c) is a view showing a modification of the body fluid diffusion unit to be described later. At least a portion of the sheet material 80 is surrounded by the press section in a plan view.

The sheet material 80 is composed of at least a mixed material 81 in which an absorbent material containing a pulp and a Chinese medicine material are mixed, and an exterior sheet 82 disposed on the surface of the sheet on the side of the sheet side and on the side of the laminate side of the sheet.

The density of the sheet material 80 is preferably higher than the density of the absorbent core 32. Specifically, the density of the absorbent core of the present embodiment is 0.5 to 0.10 g/cm ³ , and the density of the sheet material is 0.10 to 0.30 g/cm ³ .

By the density of the sheet member 80 being higher than the density of the absorbent core 32, the body fluid inhalation property of the sheet material is improved, and the menstrual blood retained in the skin can be instantaneously sucked. Further, since the density of the sheet material is high, even when the absorbent article is used for a long period of time or the like, the rigidity is hardly lowered when exposed to an environment having high humidity, and the sheet material 80 can be prevented from being wrinkled.

Since the density of the sheet material 80 is high, the diffusibility of the body fluid becomes high, and even a small amount of menstrual blood can be brought into contact with most of the traditional Chinese medicine materials. In general, the drug component of the sheet material is easily and efficiently diffused by contact with a liquid. Therefore, by increasing the diffusibility of the sheet material 80, even a small amount of menstrual blood can exert the effect of more traditional Chinese medicine components.

Further, in the region between the sheet material in the width direction and the first press portion, the sheet member 80 is not disposed, and the press portion is not formed. Therefore, the region between the sheet material in the width direction and the first press portion has a lower density than the region in which the sheet material is disposed, and has a lower density than the region in which the first press portion is formed.

In general, in the case where a large amount of menstrual blood is discharged at a time, the menstrual blood does not pass through the high-density sheet material but moves on the surface sheet. At this time, by providing a low-density region between the sheet material and the first press portion, the menstrual blood moving on the surface sheet can be sucked into the absorber side via the low-density region. because Thus, side leakage can be suppressed.

Further, the sheet material 80 is formed with a body fluid diffusion portion 83 that diffuses the body fluid toward the longitudinal direction of the absorbent article. The middle-medicine component contained in the sheet material is easily contacted with the body fluid to easily release its components. By diffusing the body fluid in contact with the sheet material in the longitudinal direction, it is possible to release a component of the drug material in a wider range and to improve the effect of the Chinese medicine component.

The body fluid diffusion portion 83 can be formed by a concave portion that compresses the outer sheet in the thickness direction or a hole portion formed in the outer sheet. The concave portion or the hole portion may be continuously formed in the longitudinal direction as shown in Fig. 5(a), or may be discontinuously formed at intervals in the longitudinal direction as shown in Fig. 5(c). For example, by the structure in which the concave portion or the hole portion is continuous in the longitudinal direction, even a small amount of body fluid easily spreads toward the longitudinal direction of the product, and the composition of the traditional Chinese medicine material tends to spread throughout the entire body. In addition, when the concave portion or the hole portion is not continuous in the longitudinal direction, the wearer is less likely to feel the hardness of the concave portion or the hole portion when touched from the surface sheet side, and the mounting feeling can be improved.

The body fluid diffusion unit 83 according to the present embodiment is a recess in which the outer sheet 82 is compressed in the thickness direction, and is continuously formed in the longitudinal direction. By forming the concave portion in this manner, the body fluid can be diffused in the longitudinal direction by the concave portion.

Further, the sheet 80 of the sheet member 80 is composed of a thin fabric or a non-woven fabric. This embodiment is composed of a thin fabric having a basis weight of 14 g/m ² . The exterior sheet 82 and the mixed material 81 may or may not be joined by an adhesive or the like.

Further, the hardness of the absorbent article or the like can be made, for example, The measurement was carried out by the GURLEY method prescribed in JIS-1096. Further, the basis weight and density of the absorber can be measured, for example, by the following measurement methods. The absorbent article packaged in the package is opened, and the folded absorbent article is unfolded, and the thickness and area of the portion for measuring the basis weight and density are measured. Then, the portion for measuring the basis weight and the density was cut out from the absorbent article to measure the weight of the cut portion. Next, the surface sheet, the back sheet, and the like, except for the absorber, are removed from the cut-out portion to measure the weight of the absorber. The basis weight was calculated from the weight of the absorbent body and the area of the portion for measuring the basis weight and density. The density is calculated based on the basis weight and thickness.

Further, the thickness can be measured by a measurement method as described below. Specifically, the sampled absorbent article is immersed in liquid nitrogen and frozen, and then cut with a razor, and returned to normal temperature, and then measured at a magnification of 50 times using an electron micromirror (for example, Keyence VE7800). Here, the reason why the sampled absorbent article is frozen is to prevent thickness variation caused by compression at the time of cutting.

Next, a part of the manufacturing method of the absorbent article 1 configured as described above will be described. In addition, there are methods that are not described, and existing methods can be used. The method for producing an absorbent article is the first step of performing a surface sheet forming process. Specifically, the surface sheet and the side sheet 41 are bonded, for example, by heat welding.

Next, the second step performs a sheet forming process. Specifically, the Chinese medicinal material and the absorbing material are mixed to form a mixed material, and the mixed material is placed between the exterior sheets.

The third step performs an absorber forming process. Specifically, the absorbent body 30 is formed by molding a pulp of an absorbent body material by a forming drum. Further, the manufacturing processes of the first step to the third step may be in different orders.

The fourth step performs the bonding process. Specifically, the joining process is a joining of a surface sheet and a side sheet joined in the first step, a sheet formed in the second step, and an absorbent body formed in the third step.

The fifth step is to carry out the pressing process. Specifically, the absorber 30 and the surface sheet 10 are compressed in the thickness direction to form a press portion.

The sixth step performs a back sheet bonding process. Specifically, the absorber, the surface sheet, and the like which form the press section, and the back sheet are joined. After bonding the back sheet, a process of applying an adhesive is provided. According to the above process, the absorbent article according to the embodiment can be manufactured.
