Abstract: 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.

Abstract: A composite sheet comprising a liquid impermeable sheet and a nonwoven fabric joined to each other by an adhesive composition, the liquid impermeable sheet having a thickness of 15 to 40 .mu.m; the nonwoven fabric having a fiber diameter of 1.5 to 3.5 deniers and a basis weight of 10 to 35 g/m.sup.2 ; and the adhesive composition comprising not less than 20% by weight of an amorphous poly-.alpha.-olefin (APAO) having a melt viscosity of 500 to 10,000 cps at 180.degree. C. and applied at an amount of 0.5 to 7 g/m.sup.2.

Abstract: The shorts type disposable diaper (1) of the present invention is characterized by a plurality of elastic members (4) provided at the urination point (40) located below the body-surrounding portion (30) and in the vicinity of the urination portion of the wearer, thereby forming continuous gathers in the width direction of the diaper. The shorts type disposable diaper (1) is also characterized by a plurality of elastic members (31) provided at the body-surrounding portion (30) in such a manner that the interval of the elastic members (31) becomes narrower towards the waist opening portion (10) and that the elongation of the elastic members (31) increases towards the waist opening portion (10).
