摘要：

In order to provide to a particularly useful water-absorbent resin powder of hygienic articles, water-absorbent resin powder, includes a polyacrylic acid (salt)-basis water-absorbing resin when a main component is surface-crosslinked, meets (1) to (3) below:The ratio of (1) one water-absorbent resin powder has a granularity, and no less than 150 microns and less than 850 microns are no less than 90 weight %； (2) it is no more than 42 seconds according to an absorbent time of a vortex method； With(3) one modulus of elasticity indexes (600-500) are no less than 5500.
