Water-absorbent resin particles 10a, in which a gel flow rate measured by the following procedures having (1) to (3) is 10 to 70 g/min:(1) mixing 1 part by mass of the water-absorbent resin particles and 199 parts by mass of water to obtain a gel,(2) accommodating the gel in a funnel in a state where a circular lower end opening with a diameter of 8 mm in the funnel is closed, and(3) measuring an outflow amount of the gel per unit time after a lapse of 3 minutes from opening of the lower end opening as the gel flow rate. |
