PROBLEM TO BE SOLVED: To provide an absorbent pad which is easily fit to a body in wearing and is attached to the inside of a diaper.SOLUTION: An absorbent pad attached to the inside of a diaper includes: a longitudinal direction L a width direction W perpendicular to the longitudinal direction L a thickness direction perpendicular to the longitudinal direction L and the width direction W a surface sheet a rear surface sheet an absorber 30 between the surface sheet and the rear surface sheet and a locking part 90 which extends in the width direction W on a non-skin surface side of the rear surface sheet and locks on the diaper. A rigidity changing part 46 which gives a difference in rigidity is provided on a non-skin surface of the absorber 30 or on a side close to the non-skin surface with respect to the absorber 30 in a region overlapped with the locking part 90 in the thickness direction.SELECTED DRAWING: Figure 5
