Abstract
An absorbent article includes an absorber having a front surface side sheet, a back surface side sheet disposed on the back surface side of the front surface side sheet, cells each of which is surrounded by bonded portions of the front surface side sheet and the back surface side sheet and inside each of which the front surface side sheet and the back surface side sheet are not bonded, and particulate materials which include superabsorbent polymer particles and which are contained in each of the cells. The bonded portions are arranged in continuous line shapes or dotted line shapes so as to form same-sized regular hexagons, which connect each other as unit shapes to be a honeycomb shape. All the cells are the same-sized regular hexagonal cells each of which is surrounded by the bonded portions.
