    • Provided is a water-decomposable absorbent article including 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. The absorbent article includes 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 the 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, both in wet and in dry.
