An absorbent article has a front surface side sheet and a back surface side sheet disposed on a back surface side of the front surface side sheet. A large number of cells are formed by bonding the front surface side sheet and the back surface side sheet. A particulate material containing super absorbent polymer particles is accommodated in the cell to form an absorber. At least a part of the particulate material containing the super absorbent polymer particles is not fixed to at least one of the front surface side sheet and the back surface side sheet. In at least one of the front surface side sheet and the back surface side sheet, sites other than the sites where the sheets are bonded each other are shrunk into a pleat shape.
