In the method, a molar neutralization degree X of the partially neutralized product (A) is set larger than a molar neutralization degree Y of the partially neutralized product (B), and also a difference between the molar neutralization degree X and the molar neutralization degree Y is set to 5% or more. The dispersing agent usable herein is at least one member among those of a surfactant and a polymer-type dispersing agent. The water-absorbent resin produced by this method suppresses odor originating from a dispersion medium and odor generated with the lapse of time after absorption of a body fluid or the like.
