Claim Text:
1. A water-absorbent sheet structure comprising a structure in which an absorbent layer comprising a water-absorbent resin composition comprising a water-absorbent resin (A) and a water-absorbent resin (B) is sandwiched with fibrous webs from an upper side and a lower side of the absorbent layer, wherein the water-absorbent resin (A) and the water-absorbent resin (B) are contained in a total amount of from 100 to 1,000 g/m 2 , and that the water-absorbent resin (A) and the water-absorbent resin (B) have the following properties: (1) the water-absorbent resin (A) having a water-retention capacity of saline solution (Ra) from 25 to 55 g/g; (2) the water-absorbent resin (B) having a water-retention capacity of saline solution (Rb) from 20 to 24 g/g; and (3) Ra and Rb satisfy the relationship: Ra−Rb≧5 (g/g) wherein the water-absorbent resin (A) and the water-absorbent resin (B) are in a mass ratio, the water-absorbent resin (A): the water-absorbent resin (B), of from 90:10 to 80:20.
