Abstract: Provided is a method for producing an absorbent article comprising a water-absorbing resin having an excellent initial water absorption speed under load even substantially without adding a liquid permeability enhancer. The method steps for producing the water-absorbing resin includes the step of polymerizing a monomer while adding certain polyalkylene glycol thereto so as to generate, during or after the polymerization, a crosslinked hydrogel polymer containing the polyalkylene glycol of a specific molecular weight, wherein the crosslinked hydrogel polymer has a centrifuge retention capacity within a given range and a final water-absorbing resin to be obtained has various physical properties (CRC, AAP, SFC, FSR) being within given ranges.
