PROBLEM TO BE SOLVED: To provide a water-absorptive resin whose protein adsorption is controlled and that is industrially easily producible and absorbs blood. SOLUTION: The water-absorptive resin containing a polymer of a water-soluble polymerizable monomer and a nonionic amphipathic polymer is obtained by polymerizing a mixture of a nonionic amphipathic polymer having protein adsorption inhibiting effect and an aqueous solution of a water-soluble polymerizable monomer, and the resulting absorptive resin has a semi-interpenetrating polymer network structure. The surface of the water-absorption resin has a mobile amphipathic polymer chain of an enough length for hindering adsorption of protein, and the inside of the water-absorptive resin is a mixture of the water-soluble polymerizable polymer and the amphipathic polymer.
