Since it is pressed, the pad 31 can be reliably fixed to the skin contact surface of the article 20 via the band 32 and the movable portion 46 of the leak-proof sheet 41, and the pad 31 is displaced while the article 20 is worn. Can be surely prevented. In the article 20, the inner pad 31 does not deviate from the excretion position, so that the body fluid excreted while the article 20 is worn can be reliably absorbed and retained by the pad 31, and the body fluid leaks to the outside of the pad 31. Can be prevented.

  Since a large amount of body fluid is excreted during wearing of the article 20 and the inner pad 31 cannot absorb all of the body fluid, the body fluid that has passed through the pad 31 is absorbed and held by the first core 38 of the article 20. Thus, a large amount of body fluid excreted can be absorbed and held without leaking outside the article 20. In this article 20, body fluid that cannot be absorbed by the inner pad 31 does not diffuse on the skin contact surface, and the dirt on the article 20 can be minimized.

  FIG. 11 is a perspective view of the article 70 of FIG. 6 showing a state during wearing. An example of the procedure for wearing the article 70 is as follows. The release paper 101 is peeled from the elastic band 80 to expose the adhesive 102, and the pad 79 is attached to the leak-proof sheet 83 so that the inner pad 79 is positioned in the front and rear waist regions 71 and 73 and the crotch region 72 of the article 70. And placed on the outer surface of the top sheet 76. After the end portions 111 of the pad 79 are passed between the surface sheet 76 and the band 80 against the contraction force of the band 80, the non-skin contact surface of the band 80 is attached to the outer surface of the surface sheet 108 via the adhesive 102. The band 80 and the pad 79 are connected to each other, and the pad 79 is attached to the article 70. When a male mechanical fastener is attached to the non-skin contact surface of the elastic band 80, the band 80 and the pad 79 are connected by the hook being caught by the fibers of the nonwoven fabric 113 forming the surface sheet 108. When the pad 79 is attached to the article 70, the outer surface of the back sheet 109 comes into contact with the outer surface of the top sheet 76, both end portions 111 are positioned in the front and rear waist areas 71 and 73, and both side portions 112 are both side portions 75 of the article 70. Located in. In the article 70, the pad 79 is pressed against the outer surface of the surface sheet 76 (skin contact surface of the article 70) by the contraction force of the band 80, and both side portions 112 of the pad 79 are supported by the movable portion 88 of the leak-proof sheet 83. Is done. The pad 79 is fixed to the skin contact surface of the article 70 via the band 80 and the movable portion 88 of the leak-proof sheet 83.

It can be reliably fixed to the skin contact surface, and the displacement movement of the pad 79 while wearing the article 70 can be reliably prevented. Since the band 80 of the article 70 is connected to the inner pad 79 via the adhesive 102, the pad 79 can be detached from the band 80 even if the band 80 is partially twisted or twisted by the wearer's action. There is no. Since the inner pad 79 does not deviate from the excretion position in the article 70, the body fluid excreted while the article 70 is worn can be reliably absorbed and retained by the pad 79, and the body fluid leaks to the outside of the pad 79. Can be prevented.

  Since a large amount of body fluid is excreted during wearing of the article 70 and the inner pad 79 cannot absorb all of the body fluid, the body fluid is absorbed and held by the first core 78 of the article 70, so The body fluid can be absorbed and held without leaking outside the article 70. In this article 70, body fluid that cannot be absorbed by the inner pad 79 does not diffuse on the skin contact surface, and the dirt on the article 70 can be minimized. When a male mechanical fastener having a plurality of hooks is attached to the skin non-contact surface of the free stretchable part 100 of the stretchable band 80, the band 80 is connected to the inner pad 79 via the hooks. Even if the band 80 is partially twisted or twisted by the movement of the wearer, the pad 79 is not detached from the band 80, and the pad 79 is securely attached to the skin contact surface of the article 70 through the band 80. The pad 79 can be fixed, and the displacement movement of the pad 79 while wearing the article 70 can be reliably prevented.
