Abstract
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 and having a smaller planar dimension than the back layer and the surface layer. The absorbent article includes an inner region in which the absorbent layer is present, and an outer peripheral region having the back layer and the surface layer bonded to each other without interposing the absorbent layer therebetween and being formed in a predetermined width spaced from a peripheral edge of the absorbent article. A thermoplastic water-soluble adhesive is applied in a strip shape between the back layer and the surface layer in a predetermined width along the peripheral edge in the outer peripheral region. The back layer and the surface layer are heat-sealed with the thermoplastic water-soluble adhesive disposed therebetween in the outer peripheral region.
