Summary: | A water-absorbing resin that exhibits excellent absorption performance and a high permeation rate with respect to liquids to be absorbed, and that effectively reduces liquid leakages, even in an absorbent body using a large amount of the water-absorbing resin. The water-absorbing resin is formed from a polymer of a water-soluble ethylenically unsaturated monomer, and when a cross-sectional image of the water-absorbing resin obtained by X-ray computer tomography is observed, the percent area of cavity portions in the cross-sectional image is 2-10%. The liquid flow rate index when a physiological saline liquid column flow rate test is performed on the water-absorbent resin having a particle diameter of 250 to 500 μm at 37° C. is 5-20. |
