In a water-absorbing article (especially diaper) containing a water-absorbing resin as a water-absorbing agent, its “absolute absorption amount (g)”, “liquid absorption time (particularly the second and subsequent liquid absorption times)”, “return amount (g)” The present invention provides a water-absorbing resin (water-absorbing agent) that improves the “diffusion distance (%)” and a method for producing the same. In the particulate water-absorbing agent according to the present invention, CRC, a ratio of particles of 600 μm to 150 μm defined by standard sieve classification, SST, and a difference value of SST with respect to FST are in a predetermined range. |
