Provided is an absorbent article having improved performance for preventing rewetting while suppressing lateral leaks. This absorbent article (1) has: a top sheet (10); a middle sheet (15) arranged on the non-skin-facing surface side from the top sheet; an absorbent core (31) arranged on the non-skin-facing surface side from the middle sheet; and a skin surface-side sheet (20) arranged on the skin-facing side from the absorbent core. In the absorbent article, a pair of folding lines (FL1, FL2) for folding the absorbent article so that the skin-facing surfaces of the absorbent article face each other are formed in the front-rear direction. The top sheet has a folded back section (12) that is folded back to the non-skin-facing surface side in the outer side of the middle sheet in the width direction. A joint region (R11) in which the folded back sections are joined to the skin surface-side sheet and a non-joint region (R12) in which the folded back sections are not joined to the skin surface-side sheet are provided, the non-joint region (R12) being disposed on the outer side of the joint region in the width direction. At least a portion of the non-joint region is arranged outside the folding lines in the width direction, and the folding lines are formed outside the outer edge of the middle sheet in the width direction in the non-joint region.L'invention concerne un article absorbant présentant une performance améliorée pour empêcher la réhumidification tout en éliminant les fuites latérales.
