PROBLEM TO BE SOLVED: To provide a humor absorption sheet capable of suppressing an occurrence of displacement, twisting, and crease.SOLUTION: A humor absorption sheet 1 includes: a surface sheet 2 and a back sheet 3 having such an external shape that a first-directional length is longer than a second-directional length orthogonal thereto an absorbent core 4 that is provided between the surface sheet 2 and the back sheet 3 and has an outer shape one-size smaller than that of the surface sheet 2 and the back sheet 3 and an adhesive layer 5 formed on the back side of the back sheet 3. The adhesive layer 5 is so formed that an adhesive area 50 is present to outer edges 33 of side edge parts 30 for at least parts of both-side side edge parts 30 and 30 in the second direction of the back side of the back sheet 3.
