An absorbent article includes a liquid permeable topsheet, a liquid-impermeable and moisture-permeable leakproof sheet, and a liquid retentive absorbent member interposed between the topsheet and the leakproof sheet. A foamed material is disposed in the absorbent member. The foamed material has a density of 5 to 35 kg/m3, a no-load thickness of 1 to 10 mm, and a compressive recovery of 60% or more in terms of (b/a×100), wherein a is a thickness (mm) measured after 24-hour standing with no load applied, and b is a thickness (mm) measured after 24-hour compression under a load of 180 gf/cm2 followed by 30-minute standing with no load applied. The foamed material is fixed at the prescribed position with an adhesive, which has been applied to have applied parts and unapplied parts.
An absorbent article comprising a liquid permeable topsheet, a liquid-impermeable and moisture-permeable leakproof sheet, and a liquid retentive absorbent member interposed between said topsheet and said leakproof sheet, wherein a foamed material is disposed between said leakproof sheet and said absorbent member, between said topsheet and said absorbent member, inside said absorbent member or in plural positions thereof, said foamed material having a density of 5 to 35 kg/m3, a no-load thickness of 1 to 10 mm, and a compressive recovery of 60% or more in terms of (b/a×100), wherein a is a thickness (mm) measured after 24-hour standing with no load applied, and b is a thickness (mm) measured after 24-hour compression under a load of 180 gf/cm2 followed by 30-minute standing with no load applied, and said foamed material is fixed at a prescribed position with an adhesive which has been applied to substantially the entire surface of at least one side of said foamed material or substantially the entire contact area of a member to be brought into contact with said foamed material in such a manner that the adhesive is distributed substantially uniformly while providing applied parts and unapplied parts, and wherein said foamed material is urethane foam.
