Water disintegratable absorber and absorbent article

摘要

An absorber and an absorbent article which have excellent leak proof property during use and water disintegratability after disposal. The water disintegratable absorber includes a water disintegratable absorber layer and a water insoluble resin layer. The amount of water absorption of the water disintegratable absorber layer is 300 g/m2 or more and tear strength in the plan view direction of the water insoluble resin layer is 0.15 N/40 mm or less in a first direction as well as a second direction that is orthogonal to the first direction.
