Abstract:
A water-decomposable absorbent article comprising a water-decomposable back layer, a water-decomposable and liquid-pervious surface layer, and a water-decomposable absorbent layer sandwiched between the back layer and the surface layer, wherein;the absorbent article including an outer peripheral region being formed in a predetermined width spaced from a peripheral edge of the absorbent article, and an inner region located inside the outer peripheral region, the absorbent layer and the back layer, and/or the absorbent layer and the surface layer are bonded to each other with a water-soluble or water-swellable adhesive therebetween in the inner region, and an interlayer bonding strength of the layers bonded with the adhesive in the inner region is higher than the interlayer bonding strength of the layers in the outer peripheral region, when both wet and dry, and wherein constituent layers in the outer peripheral region are bonded to each other with a water-soluble adhesive therebetween, and the amount of the water-soluble adhesive applied to a unit area of the inner region is larger than that of the adhesive applied to the unit area of the outer peripheral region.
