This absorbent article comprises an absorbent (50) having cells (55), the perimeter of each of which is surrounded by a joint (54) that joins a front sheet (51) and a rear sheet (52), and in which the front sheet (51) and the rear sheet (52) are not joined, and a particulate containing highly absorbent polymer particles (53) contained within these cells (55). The joints (54) include weak joints (54b) which can be peeled by the expansive force of the highly absorbent polymer particles (53) within adjoining cells (55), and strong joints (54a) that are not peeled by the expansive force of the highly-absorbent polymer particles (53) within adjoining cells (55). In an intermediate area in the width direction (WD) of the absorbent, a dispersion improving part (57) that comprises a vertical strong joint line (58) that continues from the strong joint (54a) in the longitudinal direction (LD), and adjoining low-expansion cells (55s) adjoining on both sides thereof, is provided.
