    • The purpose of the present invention is to provide a method for producing a water absorbent resin in which a water absorbent resin having excellent properties can be obtained effectively. The present invention relates to a method for producing a polyacrylic acid (salt)-based water absorbent resin, which includes a polymerization step of polymerizing an aqueous monomer solution containing a polymerization inhibitor, acrylic acid (salt) and an internal cross-linking agent to produce a water-containing gel-like cross-linked polymer, a gel-crushing step of performing the gel-crushing of the water-containing gel-like cross-linked polymer simultaneously with or subsequent to the polymerization to produce a particulate water-containing gel-like cross-linked polymer, and a drying step of supplying the particulate water-containing gel-like cross-linked polymer to a continuous through-flow belt-type dryer by a traverse conveyor to dry the particulate water-containing gel-like cross-linked polymer, in which the belt temperature of the traverse conveyor is 40 to 120° C. and/or the water soluble component in the particulate water-containing gel-like cross-linked polymer on the traverse conveyor is 10% by weight or less and the water soluble component is increased after the drying step.
