The 2nd adhesive agent 3 in the diaper 1 has the weak adhesive agent 3a and the strong adhesive agent 3b arrange|positioned in the mutually different site|part. As the second adhesive 3, a plurality of adhesives for bonding the lower core sheet and the back sheet with different adhesive strengths may be used. For example, as the second adhesive, it is preferable that the adhesive strength when wet is different between the adhesive arranged in the central region of the width direction Y and the adhesive arranged in the side regions sandwiching the central region, and more preferably In each of the side regions, an adhesive having a stronger adhesive strength when wet is arranged than the adhesive arranged in the central region. According to this configuration, when the absorber 11 is wetted by the excretion liquid, the central portion of the absorber 11 in the width direction Y is easily stretched in the width direction Y, and the swelling resistance of the absorber 11 can be further suppressed. The adhesion strength at the time of wetting is the adhesion strength under the assumption that the absorber 11 is in contact with the excretory fluid and is wetted. In addition, the magnitude|size of the adhesive strength at the time of wetting was confirmed by the method shown below. <Test for confirming the magnitude of adhesive strength> An arbitrary portion where the absorptive core 13 is present is cut along the width direction Y of the diaper 1, and the portion corresponding to the lower core wrapping material 14b of the cut surface is taken as the center It is gradually soaked with water using a sprayer. A force is applied in a direction in which the lower core wrapping material 14b and the back sheet 15 are peeled off, and it is checked whether the lower core wrapping material 14b and the back sheet 15 are peeled without being broken. This operation is repeated until the lower core sheet 14b and the back sheet 15 are completely peeled off. From the amount of water impregnation when the lower core sheet 14b and the back sheet 15 are completely peeled off, it is possible to judge the magnitude of the adhesive strength when wet. In this method, peeling of the lower core sheet 14b and the back sheet 15 occurs in the disposition area of the weak adhesive 3a with a small amount of water impregnation in the disposition area of the strong adhesive 3b. The weak adhesive 3a is preferably arranged in the central area M of the core material 14b on the lower side in the width direction Y, and the central area M is preferably arranged in the maximum length W14b of the core material 14b on the lower side in the width direction Y.

Moreover, it is preferable to arrange|position the strong adhesive agent 3b in the 2 areas on both sides when the maximum length W14b of the upper and lower side core material 14b in the width direction Y is divided into three equal parts. In the diaper 1, the back surface sheet 15 is provided with the leak-proof sheet 15a and the exterior nonwoven fabric 15b. As shown in FIGS. 3 and 4 , the leak-proof sheet 15a and the outer nonwoven fabric 15b are joined via the third adhesive 4 arranged in stripes. The third adhesive 4 is an adhesive for joining the leak-proof sheet 15a and the outer nonwoven fabric 15b. Furthermore, the third adhesive is also a term used for the convenience of explaining the present invention, and as the third adhesive, the same adhesive as the first or second adhesive described above may be used, or a different type of adhesive may be used. agent. The 3rd adhesive agent 4 is arrange|positioned at intervals in the width direction Y by the some 3rd adhesive agent arrangement|positioning part 40 in which the 3rd adhesive agent 4 is arrange|positioned. That is, the 3rd adhesive agent arrangement|positioning part 40 and the 3rd adhesive agent non-arrangement part 45 in which this 3rd adhesive agent 4 is not arrange|positioned are alternately formed in the width direction Y, and are respectively extended in the longitudinal direction X, and are formed. As shown in FIGS. 3 and 4 , the third adhesive placement portion 40 may be fixed or not, but preferably fixed as in the present embodiment. The third adhesive agent non-arrangement portion 45 exists between the third adhesive agent arrangement portions 40, and in this portion, the leakage preventing sheet 15a and the exterior nonwoven fabric 15b are not joined. Hereinafter, the region in which the third adhesive agent 4 is arranged in stripes, that is, the region including the third adhesive agent arrangement portion 40 and the third adhesive agent non-arrangement portion 45 is also referred to as a third stripe arrangement region 41 . When the leak-proof sheet 15a and the outer non-woven fabric 15b are joined by the third adhesive 4 arranged in stripes as described above, the outer non-woven fabric 15b and the outer non-woven fabric 15b can be kept while wearing (wearing) or during wearing. The joint strength of the drain sheet 15a softens the touch of the outer nonwoven fabric 15b, especially the non-skin-facing surface of the outer nonwoven fabric 15b. Moreover, when using the thing which has moisture permeability as the leak-proof sheet 15a, since the fall of moisture permeability can be suppressed, the diaper 1 can be made less likely to be stuffy. Moreover, when the 3rd adhesive agent non-arrangement part 45 and the said non-adhesive part 5 are overlapped in the planar view of the diaper 1 (absorbent article), the swelling inhibition of the said absorber 11 can be suppressed further. Hereinafter, the portion where the third adhesive agent non-arrangement portion 45 and the non-adhesive portion 5 overlap each other is also referred to as a non-adhesive overlapping portion 6 .
