A water-absorbent sheet comprising a structure comprising at least an absorbent layer containing a water-absorbent resin, sandwiched between two or more sheets of a hydrophilic nonwoven fabric, wherein the water-absorbent sheet is subjected to wavy embossing 2 and linear embossing 4, wherein a branched structure formed by the wavy embossing 2 and the linear embossing 4 has an approximate Y-shape-form, and wherein the edge portion contouring along the longitudinal direction of the water-absorbent sheet 1 comprises non-embossing regions W2 and W2', and further wherein an areal percentage of embossment provided on the water-absorbent sheet 1 is from 3 to 25% of an entire area of the water-absorbent sheet 1 . According to the present invention, effects are exhibited that a water-absorbent sheet that has a fast permeation rate of a liquid but does not cause a liquid leakage can be provided by subjecting the water-absorbent sheet to a specified embossing shape, even for a water-absorbent sheet containing a very small amount of pulps.
