Further, the side panel 3 is attached to the front end side of the side panel 3, and each elastic member 33 is extended from the front end side by the adhesive layer 31b'. The side sheet 31 is fixed to the side, and is fixed from the second side sheet 32 side by the front end side adhesive layer 36. In other words, each of the elastic members 33 is fixed to both of the first and second side sheet members 31 and 32. In this manner, each of the elastic members 33 is fixed to both ends of the first and second side sheet sheets 31 and 32 at the end portion of the side of the absorbent body 2 or the vicinity thereof, and is at the end portion on the side of the front side of the side sheet 3 or The vicinity thereof is also fixed to both the first and second side sheet members 31 and 32. Therefore, in the diaper 1 of the present embodiment, since the elastic members 33 disposed in the side sheets 3 are reliably fixed to the first and second side sheet members 31 and 32, even when the diaper 1 is worn, the diaper 1 is excessively stretched. The side panel 3 also does not easily cause peeling of the elastic member 33.

As shown in FIG. 4, the main body side extension adhesive layer 31a' and the main body side adhesive layer 35 are preferably the same as the positions of the end portions on the center side in the width direction X of the side sheets 3. In place of or in addition to this, as shown in FIG. 4, the distal end side extension adhesive layer 31b' and the distal end side adhesive layer 36 preferably have the same position of the end portion on the center side in the width direction X of the side panel 3. By adopting such a configuration, it is advantageous to further securely fix the elastic member 33 to the first and second side sheet members 31 and 32. From the viewpoint of making the effect more conspicuous, the width of the main body side extension adhesive layer 31a' and the width of the front end side extension adhesive layer 31b' in the width direction X of the side sheet 3 are each independently 3 mm or more. Especially good is 5mm or more. The upper limit is 15 mm or less, and particularly preferably 10 mm or less. For example, the width is preferably independently 3 mm or more and 15 mm or less, and more preferably 5 mm or more and 10 mm or less.

Moreover, as shown in FIG. 4, the main body side adhesive layer 35 is formed so that the adhesive layer 31a' and the main body side laminated structure part 31A extend over the main body side. As a result of this, an advantageous effect of further fixing the side panel 3 and the absorbent body 2 can be obtained. Further, as shown in FIG. 4, the distal end side adhesive layer 36 is formed so as to extend over the adhesive layer 31b' and the distal end side laminated structure portion 31B across the distal end side. As a result of this, an advantageous effect of further fixing the side panel 3 and the hook tape 4 can be obtained.

One piece of the three-dimensional protective forming sheet 21b joins the upper side joint portion 66. Specifically, in the upper joint portion 66, the surface on the inner surface P side of the two surfaces of the second side sheet 32 is bonded to the sheet for forming the three-dimensional protective sheet by the inner surface side adhesive layer 66a. . Further, the position at which the upper side joint portion 66 of the side panel 3 is formed and the position at which the main body side adhesive layer 35 is formed overlap in the thickness direction of the diaper 1. When the position where the upper joint portion 66 is formed and the position where the main body side adhesive layer 35 is formed overlap in the thickness direction of the diaper 1, it is advantageous in terms of improving the strength in the vicinity of the root portion of the side panel 3. On the other hand, when the strength near the root of the side panel 3 is sufficiently obtained, instead of this, as shown in Fig. 5, the formation position of the upper joint portion 66 and the formation position of the adhesive layer 35 on the main body side may be employed. The form is not overlapped in the thickness direction of the diaper 1.

Moreover, as shown in FIG. 4, the side sheet 3 in the diaper 1 of the first embodiment is attached to the absorbent body 2 side in the diaper width direction (X direction), and has the first side sheet 31 and the non-skin side. The sheet 22 engages the lower side joint portion 62. Specifically, in the lower joint portion 62, the surface on the outer surface Q side of the two surfaces of the first side sheet 31 is interposed between the outer surface side adhesive layer 62a and the non-skin side sheet 22 The leakage preventing sheet 22a and/or the outer layer non-woven fabric 22b are joined. Further, the position at which the lower side joint portion 62 of the side panel 3 is formed and the position at which the main body side adhesive layer 35 is formed overlap in the thickness direction of the diaper 1. Further, as shown in Fig. 4, in the diaper 1 of the first embodiment, the side sheet 3 is formed at the lower side joining portion 62 of the side sheet 3 and the body is reinforced by the presence of the main layer side interlayer adhesive layer 31a. The formation position of the side laminate structure portion 31A overlaps in the thickness direction of the diaper 1.
