By forming the non-stretchable portion 38 by pasting the non-stretchable sheet 62 on a part, the size of the stretchable portion 37 can be easily changed by changing the bonding area of the non-stretchable sheet 62.

  If each non-stretchable sheet 62 is not provided up to the side edge of each fastening portion main body 45, 48 of the stretchable member 61 constituting each breathable panel 35, the side edge of these fastening portion main bodies 45, 48 It becomes a knob part which has a stretching property, and each fastening part 41 and 42 becomes easier to pinch.

  In the eleventh embodiment, for example, the elastic member 61 may be bonded to the surface of each flap sheet 6 or bonded to the back surface of the exterior sheet 7.

  Moreover, in each said embodiment, it is also possible to make the absorbent article main body 1 into the structure which does not provide the flap sheets 6 and 6 or the exterior sheet | seat 7. FIG. In this case, the main parts such as the air vents 27 and the air permeable panels 35 are constituted by the top sheet 3 or the back sheet 4 instead of the flap sheets 6 and 6 or the exterior sheet 7. Thus, the same operational effects as those of the above embodiments can be obtained.

  Further, the ventilation portion may be formed only on the back side portion 11 without being formed on the ventral side portion 13.
