With regard to a method for producing a water absorbent resin by drying a particulate hydrogel crosslinked polymer having a high solid content concentration (of 45% by weight or more, further 50% by weight or more, and particularly 55% by weight or more), to provide a method for efficient drying of a water absorbent resin having maintained/improved physical properties.A production method in which a through-circulation belt type dryer or a through-circulation stationary batch type dryer is used in the drying step and the drop and scatter ratio of a particulate hydrogel crosslinked polymer is set to 1% by weight or less.
