The purpose of the present invention is to provide a water-absorbent resin having excellent absorption properties in a localized absorption area. Provided is a water-absorbent resin composed of a polymer of water-soluble ethylenically unsaturated monomers, wherein the physiological saline absorption rate is 5-30 seconds, and the diffusion absorption index under load expressed as a physiological saline absorption capacity under a load of 1.96 kPa in a local area of 78.5 mm2 is at least 10 g/g. This water-absorbent resin has excellent absorption properties in a localized absorption area. |
