Provided is an absorbent article that can suppress leakage from the rear of the article when a user is lying face up. An absorbent article (1) has: a first curved part (41) that extends in the width direction (W) and that is further to the rear side than the longitudinal direction (L) center of a wing (3) and further to the front side than the rear edge of an absorption core and a second curved part (42) that extends in the width direction (W) and is positioned further rearward than the first curved part (41). The absorbent article (1) has: a first region (R1) that is adjacent to the first curved part (41) to the front of the first curved part (41) a second region (R2) that is adjacent to the second curved part (42) to the rear of the second curved part (42) and an intermediate region (R3) that is positioned between the first curved part (41) and the second curved part (42) in the longitudinal direction (L). The weight per unit area of the absorption material in the intermediate region (R3) is lower than the weight per unit area of the absorption material in the first region (R1) and is lower than the weight per unit area of the absorption material in the second region (R2). The length of the intermediate region (R3) in the longitudinal direction (L) is longer than the thickness of an absorption body (30) at the portion of the first region (R1) that is adjacent to the first curved part (41).
