The present invention provides a method for producing a water-absorbing resin powder. The method includes a polymerization step, a drying step, a pulverization step, a classification step, and a surface cross-linking step. It further includes an additional step, performed before the surface cross-linking step, in which at least part of the classified polymer is supplied again to the same or a different pulverization step. The circulation pulverization ratio in the pulverization step is higher than 1.50.
