Abstract
An absorbent article includes an absorber including cells, each of which is surrounded by bonded portions of a front surface side sheet and a back surface side sheet and in each of which the front surface side sheet and the back surface side seat are not bonded, and including superabsorbent polymer particles contained in each of the cells. The bonded portions are arranged in dotted line shapes according to a pattern in which same-sized octagonal portions having all interior angles of 135°, and having two pairs of opposite sides whose facing directions are mutually orthogonal are equal in length, and diamond-shaped portions each having equal length of all sides and being formed in portions among the octagonal portions, are arranged without any space in the front-back direction (LD) or the width direction (WD).
