An absorbent sheet 10 of the invention is a thin sheet having a first surface 10 A and a second surface 10 B and containing a fibrous material 11 and superabsorbent polymer particles 12 . The polymer particles 12 are dispersed in the thickness direction of the absorbent sheet 10 in a state of being held by the fibrous material 11 . When the portion in the thickness direction of the absorbent sheet 10 where the polymer particles 12 are dispersed is divided into regions by at least one plane perpendicular to the thickness direction of the sheet 10 , the average particle size of the superabsorbent polymer particles 12 dispersed in each region decreases from the region that is the nearest to the first surface 10 A to the region that is the nearest to the second surface 10 B of the absorbent sheet.
