Provided is a method for efficiently producing recycled water-absorbing resin particles from, as a raw material, discarded water-absorbing resin particles derived from used sanitary supplies, etc., the recycled water-absorbing resin particles having decreased little in absorption property and having various excellent properties. The method for producing water-absorbing resin particles of the present invention comprises a polymerization step (I) in which an aqueous gel containing a crosslinked polymer (A) of a water-soluble vinyl monomer (a1) is obtained, a gel reduction step (II) in which the aqueous gel is reduced into particles to obtain aqueous-gel particles, a step (Va) in which resin particles including the crosslinked polymer (A) and obtained from the aqueous-gel particles are mixed with a surface-crosslinking agent (d), and a reaction step (Vb) in which the surface-crosslinking agent (d) is reacted. |
