An absorbent sheet, wherein: an absorbent polymer is provided inside a first space region where a periphery of the first space region is partitioned between a first sheet and a second sheet by a partition portion formed by bonding the first sheet and the second sheet, a pair comprising only a first resistance portion row and a second resistance portion row is formed in the first space region by bonding the first sheet and the second sheet, wherein each resistance portion row increases resistance to gravity movement of the absorbent polymer in the first space region; each resistance portion row comprises a plurality of resistance portions provided at intervals in a first direction, each resistance portion comprising a linear or straight dotted line shape; the first resistance portion row and the second resistance portion row are separated in a second direction, wherein the second direction intersects the first direction; each resistance portion of the first and the second resistance portion rows intersects the first direction and the second direction at an incline, wherein an inclining direction of the resistance portions of the first resistance portion row intersects an inclining direction of the resistance portions of the second resistance portion row; and a first tip of the first resistance portion row and a second tip of the second resistance portion row are arranged alternately in the first direction, and a first spacing portion through which the absorbent polymer can pass is provided between the first tip and the second tip.
