A water absorbent resin that can be suitably used for a thin absorbent article having an increased amount of water absorbent resin is immobilized, and has a low swelling regulation by immobilization. The absorber of the present invention is a water absorbent in which a water absorbent resin layer containing a water absorbent resin as an essential material is fixed to a substrate by a hot melt adhesive, and at least the layer of the substrate and the water absorbent as a means for solving the problem. It is a laminated body which has three layers of a resin layer and the said hot-melt adhesive agent, The mean porosity at the time of saturated swelling under no load of the said absorber is 30 to 70%, and the mean pore radius is 100 to 300 micrometers, It is characterized by the above-mentioned. It is done.n n n n Water Absorbency, Hydrophilicity, Saturated Swelling, Absorbent, Swelling Gel, Hot Melt Adhesive, No Load, Porosity, Pore Radius, Saturation Swelling, Elongation |
