The present invention relates to a water-absorbent resin particle including a crosslinked polymer having, as a monomer unit, at least one ethylenically unsaturated monomer selected from the group consisting of (meth)acrylic acid and a salt thereof, a ratio of the (meth)acrylic acid and the salt thereof being 70% to 100% by mol with respect to a total amount of the monomer unit in the crosslinked polymer, in which a water-permeable rate is 0.40 to 2.50 g/sec.
