Patent ID: 7717894

Claim:
A liquid-absorbent sheet comprising: a liquid-absorbent surface material comprising a pulp; a liquid-absorbent nonwoven fabric; a liquid-absorbent rear material comprising a pulp; a super absorbent polymer; an A layer which is disposed between the liquid-absorbent surface material and the liquid-absorbent nonwoven fabric; and a B layer which is disposed between the liquid-absorbent nonwoven fabric and the liquid-absorbent rear material, wherein the total amount of the super absorbent polymer is 200 to 400 g/m 2 , which is allocated in the A layer at 30 to 50% by mass, the liquid-absorbent nonwoven fabric layer at 0 to 40% by mass, and the B layer at 30 to 70% by mass; and wherein the content ratio of the super absorbent polymer in the A layer is less than or equal to the content ratio of the super absorbent polymer in the B layer.
