[0016] Hereinafter, an auxiliary member and an absorbent article including an auxiliary member according to an embodiment of the present invention will be described with reference to the drawings. Note that the configurations of the following embodiments are merely examples, and the present invention is not limited to the configurations of these embodiments.

[0017] <Embodiment> First, an absorbent article provided with an auxiliary member will be described.

[0018] In this embodiment, for a tape-type disposable diaper (an example of an "absorbent article" as referred to in this application, hereinafter simply referred to as a "diaper"), the direction connecting the front body portion arranged opposite the wearer's abdomen and the rear body portion arranged opposite the wearer's back is defined as the longitudinal direction. Between the front body portion (one side in the longitudinal direction) and the rear body portion (the other side in the longitudinal direction) (the center in the longitudinal direction) is located the crotch portion which is arranged under the wearer's crotch (opposed to the crotch). Furthermore, when the diaper is worn by a wearer (hereinafter abbreviated as "worn state"), the side facing the wearer's skin (the inner side when worn) is defined as the skin-facing side, and the side opposite the skin-facing side (the outer side when worn) is defined as the non-skin-facing side. Furthermore, the direction connecting the skin-facing side and the non-skin-facing side is defined as the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is defined as the width direction. In addition, the view from the thickness direction is defined as a planar view.

[0019] FIG. 1 is a perspective view of a diaper according to the present embodiment. The diaper 1 has a crotch region 1B, which corresponds to the crotch of the wearer covering the pubic area when worn, a front body region 1F, which is located in front of the crotch region 1B and corresponds to the front body of the wearer, and a back body region 1R, which is located behind the crotch region 1B and corresponds to the back body of the wearer. Tapes 2L and 2R are provided on both the left and right edges of the back body region 1R, which can be attached to a front patch 2F (an example of an "attached part" of an "absorbent article" in this application) provided on the non-wearer side surface of the front body region 1F. When the tapes 2L and 2R are attached to the front patch 2F with the front body region 1F positioned on the wearer's abdominal side and the back body region 1R positioned on the wearer's back side, the diaper 1 is fixed to the wearer's body in a state of surrounding the wearer's abdominal circumference and thighs. Since the diaper 1 is fixed to the wearer's body in this manner, the wearer can stand and walk around while wearing the diaper 1.

[0020] In the diaper 1, an absorbent capable of absorbing and retaining liquid is mainly disposed near the crotch region 1B. In addition, in order to prevent the formation of a gap between the diaper 1 and the wearer's skin that can be a liquid outflow path, the diaper 1 is provided with leg gathers 3AL, 3AR at a portion surrounding the wearer's legs (thighs), and three-dimensional gathers 3BL, 3BR are provided on the inner side of the leg gathers 3AL, 3AR in the width direction of the diaper 1, and a waist gather 3R is provided at a portion surrounding the wearer's abdominal circumference. The leg gathers 3AL, 3AR, the three-dimensional gathers 3BL, 3BR, and the waist gathers 3R are in close contact with the wearer's skin by the elastic force of the elastic members. Therefore, liquid discharged from the wearer's private parts is absorbed by the absorbent of the diaper 1 without leaking out of the diaper 1. As the elastic member, a thread-like or strip-like rubber or the like can be appropriately selected.

[0021] FIG. 2 is an exploded perspective view of the diaper 1. FIG. 3 is a cross-sectional view of the diaper 1 when not worn, cut in the width direction at the center in the longitudinal direction. FIG. 4 is a plan view of the diaper 1 when stretched, viewed from the skin-facing side. The diaper 1 has a cover sheet 4 that forms an outer surface when worn. The cover sheet 4 is a sheet-like member having a substantially rectangular appearance with constrictions 4KL, 4KR at the portions corresponding to the long sides, and forms the exterior surface of the diaper 1. The constrictions 4KL, 4KR are provided at the portions where the wearer's thighs are located (leg surrounding regions 10L, 10R shown in FIG. 4). The cover sheet 4 is provided to reinforce the back sheet 5 described later and to improve the feel. For example, a nonwoven fabric made of a liquid-impermeable thermoplastic resin can be used as the material for the cover sheet 4 in order to suppress leakage of excrement. Examples of liquid-impermeable thermoplastic resins include polyethylene (PE) and polypropylene (PP). The cover sheet 4 is not limited to a single-layer structure, but may be a multi-layer structure having an inner cover sheet and an outer cover sheet.

[0022] The diaper 1 has a back sheet 5, an absorbent 6C, and a top sheet 7, which are laminated in this order on the wearer's side of the cover sheet 4. The back sheet 5, the absorbent 6C, and the top sheet 7 are all sheet-like members having a substantially rectangular appearance, and are laminated in this order on the cover sheet 4 with their longitudinal directions coinciding with the longitudinal direction of the cover sheet 4. The back sheet 5, like the cover sheet 4, is a sheet formed of a liquid-impermeable thermoplastic resin material to suppress leakage of excrement. The back sheet 5 is preferably made of a material that also has moisture permeability to suppress stuffiness when worn. The absorbent 6C is disposed in the crotch region 1B. The top sheet 7 is a sheet-like member that is disposed on the skin side of the wearer so as to cover the water-absorbing surface of the absorbent 6C. The top sheet 7 is liquid permeable in part or in its entirety. Therefore, when the diaper 1 is worn, liquid excreted from the wearer is absorbed through the top sheet 7, which may come into contact with the wearer's skin. The liquid enters the absorbent body 6C and is absorbed therein. For example, a woven fabric, a nonwoven fabric, or a porous film can be used as the material for the top sheet 7. The top sheet 7 may be hydrophilic.

[0023] The back sheet 5, the absorbent 6C, and the top sheet 7 all extend from the front body region 1F to the rear body region 1R. Therefore, when the wearer's private parts are covered with the cover sheet 4 in which the back sheet 5, the absorbent 6C, and the top sheet 7 are laminated, the longitudinal ends of the back sheet 5, the absorbent 6C, and the top sheet 7 are located on the wearer's ventral side and back side. In other words, the wearer's private parts are covered by the absorbent 6C from the wearer's ventral side to the back side. Therefore, whether the wearer is in a ventral or back-facing position when excreting liquid, the excreted liquid comes into contact with the absorbent 6C via the top sheet 7.

[0024] The diaper 1 has elastic members 4SL, 4SR for forming the leg gathers 3AL, 3AR between the cover sheet 4 and the back sheet 5 so as to stretch in the longitudinal direction of the diaper 1. The elastic members 4SL, 4SR are provided in an appropriate number (three in this embodiment) determined according to the elastic force (contractile force) required in the design of the diaper 1. As shown in FIG. 4, the leg gathers 3AL, 3AR are arranged at both widthwise end portions of the crotch region 1B, including the leg surrounding regions 10L, 10R, which are the regions where the wearer's thighs are located in the diaper 1. The leg surrounding regions 10L, 10R are arranged at both widthwise end portions of the crotch region 1B. The elastic members 4SL, 4SR are arranged in the leg gathers 3AL, 3AR.

[0025] The diaper 1 also has long, narrow, strip-like side sheets 8L, 8R. The side sheets 8L, 8R are liquid-impermeable sheets provided on the long sides of the top sheet 7. Like the cover sheet 4, the side sheets 8L, 8R have constrictions 8KL, 8KR at the locations where the wearer's thighs are located (leg-surrounding regions 10L, 10R shown in FIG. 4). The side sheets 8L, 8R have elastic members 8EL, 8ER arranged along the longitudinal direction to form three-dimensional gathers 3BL, 3BR. When the diaper 1 is worn, i.e., when the diaper 1 is U-shaped in side view, the side sheets 8L, 8R are pulled in the longitudinal direction by the contractile force of the elastic members 8EL, 8ER to rise from the top sheet 7 and become three-dimensional gathers 3BL, 3BR that prevent liquid from leaking out.

[0026] The cover sheet 4 is provided with elastic members 4C, which prevent a gap from being formed between the diaper 1 and the wearer's abdominal circumference, on the inner side in the width direction of the diaper 1 than the elastic members 4SL, 4SR and along the longitudinal direction of the diaper 1. The elastic members 4C are provided according to the elastic force (contractile force) required for the design of the diaper 1.

[0027] The diaper 1 also includes an elastic member 9ER for forming the waist gather 3R described above. The elastic member 9ER is provided between the back sheet 5 and the top sheet 7 at a position further toward the back side than the end of the absorbent body 6C. The elastic member 9ER extends between the back sheet 5 and the top sheet 7 so that the stretch direction of the elastic member 9ER is the width direction of the diaper 1. Therefore, when the tapes 2L, 2R provided on both the left and right sides of the elastic member 9ER are attached to the front patch 2F on the abdominal side of the wearer, the elastic member 9ER exerts a contractile force to bring the diaper 1 into close contact with the wearer and prevent the formation of a gap between the diaper 1 and the wearer's abdominal circumference.

[0028] The absorbent body 6C has a structure in which granular absorbent resin such as SAP (Super Absorbent Polymer), a hydrophilic polymer with a cross-linked structure that can absorb and retain water, is held in the gaps between short fibers of cellulosic fibers such as pulp fibers, rayon fibers, or cotton fibers, or short fibers that have been hydrophilically treated synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. Therefore, in the absorbent body 6C, the volume change of the absorbent resin before and after absorbing liquid is basically due to the absorbent resin being held in the gaps. Therefore, when the absorbent body 6C is viewed as a whole, it can be said that the expansion rate of the thickness of the absorbent body 6C that has absorbed liquid is not as large as the expansion rate of the absorbent resin itself.

[0029] The SAP particles of this embodiment refer to a resin composition containing SAP in a granular form. The term "SAP-containing resin composition" as used herein includes both a composition consisting of SAP alone and a composition containing SAP as the main component and containing other substances to the extent that they do not adversely affect the water absorption. Examples of "other substances" include additives (such as surface modifiers added to make the particle surface hydrophobic) and unreacted monomers remaining during the synthesis of SAP.

[0030] As shown in Fig. 4, the diaper 1 is provided with a pair of side flap portions 11L, 11R (an example of the "left and right ends" in the present application) arranged in the rear body region 1R and extending outward in the width direction of the diaper 1 beyond the absorbent body 6C. In this embodiment, the side flap portions 11L, 11R are configured to include a cover sheet 4 forming an exterior surface of the diaper 1, and side sheets 8L, 8R joined to the skin-facing side of the cover sheet 4 for forming three-dimensional gathers 3BL, 3BR. The diaper 1 is also provided with tapes 2L, 2R connected to the pair of side flap portions 11L, 11R, respectively, and attached to a front patch 2F arranged in the front body region 1F for fixing the diaper 1 to the waist of a wearer.

[0031] The tapes 2L, 2R have base ends 20L, 20R fixed to the side flap parts 11L, 11R, and tape base parts 21L, 21R extending outward in the width direction from the side flap parts 11L, 11R. The base ends 20L, 20R and the tape base parts 21L, 21R are formed of a single sheet member such as a nonwoven fabric. The base ends 20L, 20R are disposed between the cover sheet 4 and the side sheets 8L, 8R constituting the side flap parts 11L, 11R, and are bonded to at least one of the cover sheet 4 and the side sheets 8L, 8R with an adhesive. This connects the tapes 2L, 2R to the side flap parts 11L, 11R. On the other hand, the tape base parts 21L, 21R protrude from the edges of the side sheets 8L, 8R. Furthermore, hook portions 22L, 22R (an example of an "adhesive portion" of the "tape" as referred to in this application) are disposed on the skin-facing side of the tape bases 21L, 21R. The hook portions 22L, 22R are engageable with the front patch 2F. The front patch 2F has loop portions formed on its surface with which the hook portions 22L, 22R are engageable. The tapes 2L, 2R are adhered to the front body region 1F of the diaper 1 by the hook portions 22L, 22R engaging with the loop portions of the front patch 2F.

[0032] As shown in Fig. 4, the tapes 2L and 2R are relatively short. For this reason, when a wearer tries to put on the diaper 1, for example, because the wearer has contracture or is overweight, the wearer may not be able to reach the tapes 2L and 2R to the front patch 2F, making it difficult for the wearer to attach the tapes 2L and 2R to the front patch 2F. Therefore, in this embodiment, an auxiliary member is attached to the tapes 2L and 2R.

[0033] Next, the auxiliary member will be described. Fig. 5(A) is a plan view of the auxiliary member seen from one side, and Fig. 5(B) is a plan view of the auxiliary member seen from the other side. Fig. 6 is a cross-sectional view of the auxiliary member cut along the longitudinal direction at the center in the width direction.

[0034] As shown in Figure 5, the auxiliary member 12 in this embodiment is a member that is attached to the tapes 2L, 2R and functions to essentially extend the tapes 2L, 2R, and is provided with a sheet-like base material 13, a loop portion 14, and a hook portion 15.

[0035] The substrate 13 has a rectangular base 23A and extends from one end of the base 23A. It is made up of a tip portion 23B having a generally tapered shape with a narrowing width.

[0036] 6, the base material 13 is formed of a non-stretchable sheet 13A, a stretchable sheet 13B, and a non-stretchable sheet 13C. The non-stretchable sheet 13A, the stretchable sheet 13B, and the non-stretchable sheet 13C are arranged in this order in the direction from the base 23A to the tip 23B in the longitudinal direction of the auxiliary member 12. The end of the non-stretchable sheet 13A on the tip 23B side and the end of the stretchable sheet 13B on the base 23A side are overlapped and joined, and the end of the stretchable sheet 13B on the tip 23B side and the end of the non-stretchable sheet 13C on the base 23A side are overlapped and joined. As a result, a first non-elastic region 24A made of the non-elastic sheet 13A, a second non-elastic region 24B made of the non-elastic sheet 13C, and an elastic region 24C (an example of the "elastic portion" in this application) made of a portion of the elastic sheet 13B that does not overlap with the non-elastic sheets 13A and 13C are formed in the base material 13. As shown in Fig. 5, the base portion 23A of the base material 13 includes the first non-elastic region 24A, the elastic region 24C, and a portion of the second non-elastic region 24B, and the tip portion 23B includes the remaining portion of the second non-elastic region 24B.

[0037] The non-elastic sheets 13A and 13C are formed from a non-woven sheet material or a plastic film that has almost no elasticity. On the other hand, the elastic sheet 13B is formed from a non-woven sheet material that has elasticity and flexibility. For example, a sheet material in which an elastic member such as rubber thread is attached in a stretched state to a part of a non-woven sheet and the remaining part of the sheet is folded back and bonded so that the elastic member is not exposed can be used as the non-woven sheet material that has elasticity and flexibility. In addition, the non-elastic sheets 13A and 13C and the elastic sheet 13B are bonded together by adhesion using an adhesive, or by fusion bonding using heat and pressure in embossing or ultrasonic waves.

[0038] The base material 13 may be formed from a stretchable sheet and a non-stretchable sheet joined to both ends of the stretchable sheet in the longitudinal direction of the auxiliary member 12 .

[0039] The loop portion 14 functions as a hook-and-loop fastener by engaging the hook portions 22L, 22R of the tapes 2L, 2R, and is disposed on one end of the auxiliary member 12 in the longitudinal direction of one surface of the base material 13 (the upper surface of the base material 13 in FIG. 6), specifically, on the end opposite the tip portion 23B of the base portion 23A. The width of the loop portion 14 is approximately the same as the width of the base portion 23A. Similarly to the loop portion of the front patch 2F, the loop portion 14 is formed, for example, by bonding plastic threads lengthwise and crosswise to the surface of a plastic film with an adhesive. The loop portion 14 is joined to the non-stretchable sheet 13A, i.e., the first non-stretchable region 24A of the base material 13, for example, with an adhesive.

[0040] The hook portion 15 engages with the loop portion of the front patch 2F to function as a hook-and-loop fastener, and is disposed on the other end of the auxiliary member 12 in the longitudinal direction of the other surface of the base material 13 (the lower surface of the base material 13 in FIG. 6), specifically, on a part of the tip portion 23B. Since the width of the tip portion 23B is narrower than the width of the base portion 23A, the width of the hook portion 15 is narrower than the width of the loop portion 14. Similarly to the hook portions 22L and 22R of the tapes 2L and 2R, the hook portion 15 is, for example, a plastic film having plastic protrusions formed lengthwise and widthwise on the surface of the plastic film. The hook portion 15 is joined to the non-stretchable sheet 13C, i.e., the second non-stretchable region 24B of the base material 13, for example, by an adhesive.

[0041] Such an auxiliary member 12 is expandable at least in the longitudinal direction of the auxiliary member 12 due to the expandable region 24C of the base material 13. Fig. 7(A) is a plan view showing the state of the auxiliary member 12 of this embodiment when stretched in the longitudinal direction, and Fig. 7(B) is a plan view showing the state of the auxiliary member of the comparative example when stretched in the longitudinal direction. Note that the auxiliary member of the comparative example is basically Generally, it has the same configuration as auxiliary member 12 of the present embodiment. However, it is different in that auxiliary member 12 of the present embodiment has a rectangular base 23A, whereas the auxiliary member of the comparative example has a substantially tapered base.

[0042] As described above, in the auxiliary member 12 of the present embodiment, the base 23A of the base material 13, which includes at least the first non-stretchable region 24A and the stretchable region 24C, has a rectangular shape. Therefore, as shown in FIG. 7(A), even when the auxiliary member 12 is stretched in the longitudinal direction, the stretchable region 24C stretches in the longitudinal direction, and the shape of the base 23A is maintained as a rectangular shape. Also, as described above, the width of the hook portion 15 is narrower than the width of the loop portion 14. Therefore, when the auxiliary member 12 is stretched in the longitudinal direction, the base material 13 has a trapezoidal region 25 surrounded by a virtual line (in FIG. 7, a dashed line with a wide gap) connecting one imaginary end point 14A in the width direction of the auxiliary member 12 on the stretchable region 24C side of the loop portion 14 in the first non-stretchable region 24A, the other imaginary end point 14B, one imaginary end point 15A in the width direction of the auxiliary member 12 on the stretchable region 24C side of the hook portion 15 in the second non-stretchable region 24B, and the other imaginary end point 15B. At this time, for example, a stress is applied to the hook portion 15 side portion of the trapezoidal region 25 of the base material 13 in a direction inward in the width direction of the auxiliary member 12 and toward the hook portion 15 side.

[0043] 7(B), when the base 32A of the substrate 31 has a tapered shape that narrows toward the tip 32B, as in the auxiliary member 30 of the comparative example, the substrate 31 may have a portion inside the trapezoidal region 25 when the auxiliary member 30 is stretched in the longitudinal direction. Since the inner portion is subjected to a stress stronger than the above-mentioned stress, the substrate 31 may be twisted or broken starting from the inner portion.

[0044] In contrast, in the auxiliary member 12 of this embodiment, as described above, even when the auxiliary member 12 is stretched in the longitudinal direction, the base 23A of the base material 13 maintains its rectangular shape, so that the base material 13 has a trapezoidal region 25. Therefore, only a relatively weak stress is applied to the base material 13, so that it is possible to prevent the base material 13 from twisting or breaking. Furthermore, the base material 13 also has a region outside the trapezoidal region 25. When the auxiliary member 12 is stretched in the longitudinal direction, the aforementioned stress causes the outer region to warp and rise toward the surface on which the loop portion 14 is provided, making it an easy-to-grasp portion. In particular, both corners on the hook portion 15 side of the base 23A (parts surrounded by broken lines with wide gaps in FIG. 7) correspond to the aforementioned outer region, and the width of the outer region is wider, making it an even more suitable easy-to-grasp portion.

[0045] Next, a method of attaching the auxiliary member 12 to the diaper 1 will be described. Fig. 8 is a diagram illustrating a method of attaching the auxiliary member 12 to the diaper 1. Fig. 9 is a plan view of the diaper 1 and the auxiliary member 12 after the auxiliary member 12 is attached, as viewed from the skin-facing side.

[0046] As shown in Fig. 8, when the diaper 1 and the auxiliary member 12 are separate, the auxiliary member 12 is disposed near the tapes 2L, 2R so that the hook portions 22L, 22R of the tapes 2L, 2R of the diaper 1 face the loop material 14 of the auxiliary member 12. Then, the hook portions 22L, 22R of the tapes 2L, 2R are engaged with the loop portion 14 of the auxiliary member 12, and the auxiliary member 12 is brought into contact with the tapes 2L, 2R to adhere to the tapes 2L, 2R. At this time, since the loop material 14 is relatively wide, it is easy to engage the hook portions 22L, 22R of the tapes 2L, 2R with the loop portion 14 of the auxiliary member 12, and the auxiliary member 12 can be firmly adhered to the tapes 2L, 2R.

[0047] In this manner, the auxiliary member 12 is attached to the diaper 1 with the hook portion 15 of the auxiliary member 12 visible from the skin side, as shown in Fig. 9. Note that in Fig. 8, the diaper 1 and the auxiliary member 12 are separate members, but the tape 2 of the diaper 1 may be attached to the diaper 1 in advance as a product. The auxiliary member 12 may be attached to the L and 2R ends, that is, the diaper 1 and the auxiliary member 12 may be integral with each other.

[0048] Next, a method of using the auxiliary member 12 will be described.

[0049] When a wearer puts on the diaper 1 to which the auxiliary member 12 is attached, the auxiliary member 12 is placed against the front patch 2F, and as shown in FIG. 10, the hook portion 15 of the auxiliary member 12 is engaged with the loop portion of the front patch 2F of the diaper 1, thereby attaching the auxiliary member 12 to the front patch 2F. At this time, the tapes 2L and 2R are substantially in an extended state by the auxiliary member 12, so that even if the wearer has contracture or is overweight, the wearer can easily attach the tapes 2L and 2R to the front patch 2F. Moreover, since the auxiliary member 12 has a stretchable region 24C, the stretchable region 24C stretches in the longitudinal direction of the auxiliary member 12, in other words, in the width direction of the diaper 1, thereby stretching the auxiliary member 12. This makes it even easier for the wearer to attach the tapes 2L and 2R to the front patch 2F. In addition, when the auxiliary member 12 is stretched in the longitudinal direction, the region of the base material 13 outside the trapezoidal region 25, for example, both corners 26 on the hook portion 15 side of the base portion 23A described above, are warped and raised, forming a portion that is easy for the wearer to grasp. Using this easy-to-grasp portion makes it easier for the wearer to reattach the auxiliary member 12 to the tapes 2L, 2R or the front patch 2F.

[0050] Furthermore, since a flexible stretchable sheet 13B is arranged in the stretchable region 24C of the auxiliary member 12, the wearer is unlikely to feel uncomfortable when wearing the diaper 1, even if the wearer is overweight and the stretchable region 24C is in contact with the wearer's skin.

[0051] <Other embodiments> Next, other embodiments will be described. In the auxiliary member 12 according to the above embodiment, as shown in Figs. 5 and 6, the loop portion 14 is arranged at one end of one surface of the base material 13, and the hook portion 15 is arranged at the other end of the other surface of the base material 13 so that the loop portion 14 and the hook portion 15 do not overlap, but the arrangement of the loop portion 14 and the hook portion 15 is not limited to this. For example, the loop portion 14 may be arranged at one side of one surface of the base material 13 in the longitudinal direction of the auxiliary member 12, and the hook portion 15 may be arranged at the other side of the other surface of the base material 13 in the longitudinal direction of the auxiliary member 12, so that a part of the loop portion 14 and a part of the hook portion 15 overlap. Also, the loop portion 14 may be arranged over the entire one surface of the base material 13, and the hook portion 15 may be arranged over the entire other surface of the base material 13.

[0052] In addition, in the auxiliary member 12 according to the above embodiment, the base material 13 is formed from the non-stretchable sheet 13A, the stretchable sheet 13B, and the non-stretchable sheet 13C, but the material of the base material 13 is not limited thereto. For example, the base material 13 may be formed only from the non-stretchable sheet.

[0053] In the diaper 1 to which the auxiliary member 12 according to the above embodiment is attached, the hook portions 22L, 22R of the tapes 2L, 2R are engaged with the loop portions of the front patch 2F to attach the tapes 2L, 2R to the front patch 2F, but the manner of attachment of the tapes 2L, 2R to the front patch 2F is not limited to this. For example, in the diaper 1, the hook portions 22L, 22R may be replaced with an adhesive portion (an example of an "adhesive portion" of the "absorbent article" in the present application) to which an adhesive is applied on the skin-facing side of a portion of the tape bases 21L, 21R of the tapes 2L, 2R, and the front patch 2F having a loop portion may be replaced with a front patch 2F having a flat surface without a loop portion (an example of an "adhered portion" of the "absorbent article" in the present application). Then, the adhesive portions of the tapes 2L, 2R may be attached to the front patch 2F. The tapes 2L, 2R may be attached to the front patch 2F by being adhered to the tape 2L, 2R. For a diaper 1 having adhesive portions on the tapes 2L, 2R and a flat front patch 2F, the auxiliary member 12 may have a flat surface film (an example of an "adhered portion" of the "auxiliary member" in this application) provided on the end of the base portion 23A of the substrate 13 instead of the loop portion 14, and may have an adhesive portion coated with an adhesive on a part of the tip portion 23B (an example of an "adhered portion" of the "auxiliary member" in this application) instead of the hook portion 15.

[0054] In the diaper 1 to which the auxiliary member 12 according to the above embodiment is attached, the front patch 2F is provided in the front body region 1F, but the front patch 2F may not be provided in the front body region 1F and the hook portions 22L, 22R may be engageable with a part of the cover sheet 4 in the front body region 1F (an example of an "attached portion" of the "absorbent article" in this application). For a diaper 1 not provided with a front patch 2F, the hook portion 15 of the auxiliary member 12 is engaged with a part of the cover sheet 4 of the diaper 1, thereby attaching the auxiliary member 12 to the cover sheet 4.
