Further, the back sheet 3 has water repellency or liquid impermeability through which excretion liquid such as urine cannot permeate, and is formed of a film-like sheet of synthetic resin such as polyolefin such as polyethylene resin.

  The absorbent body 4 is formed of a material that can absorb excrement such as urine, for example, pulp as a main material and partly containing a substance such as a polymer absorber, and is located on the back side portion 11. It has an absorbent body part 21, an abdominal absorbent part 22 located on the ventral part 14, and an inseam absorbent part 23 located on the crotch part 13 continuously between these absorbent parts 21 and 22. ing.

  A long hole 25 is formed along the longitudinal direction at the center of the crotch absorber part 23, and the leg part 12 is notched on both sides of the crotch absorber part 23. Corresponding to the shape, notch recesses 26 and 26 are provided on both sides, and portions between both sides of the hole 25 and the notch recesses 26 and 26 are leg-line absorber portions 27 and 27.

  The hole 25 is a non-existing region of the absorbent body 4 formed along the longitudinal direction of the inseam absorber part 23, and the top sheet 2 and the back sheet 3 are joined at a position corresponding to the hole 25. A concave dent 31 is formed from the top sheet 2 side to the back sheet 3 side. That is, the recessed portion 31 is formed in a longitudinal shape along the longitudinal direction at a substantially central portion in the width direction of the crotch portion 13 between the leg portions 12 and 12.
