Abstract
A configuration in which an upper auxiliary layer of an absorber includes a super absorbent nonwoven fabric having a surface exposed on an uppermost surface of the absorber and having a Klemm water absorptiveness of 100 mm or more, first super absorbent polymer particles adjacent to a back surface of the super absorbent nonwoven fabric. The main absorption layer of the absorber is a cell absorbing sheet including second super absorbent polymer particles contained in the cells arranged at intervals. A convex bulging upward is formed at each cell in an upper sheet. The first super absorbent polymer particles are fixed to the upper surface of the upper sheet. An adhesion amount of the first super absorbent polymer particles on the upper surface of the upper sheet increases from the top of a convex toward the bottom of a valley between a convex and a convex adjacent each other.
