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).Linvention concerne un article absorbant qui peut supprimer une fuite arrière lorsquune utilisatrice est couchée sur le dos. Un article absorbant (1) comporte : une première partie incurvée (41) qui sétend dans le sens de la largeur (W) et qui est plus vers un côté arrière que le centre de la direction avant-arrière (L) dune aile (3) et plus vers un côté avant quun bord terminal arrière dun noyau dabsorption et une seconde partie incurvée (42) qui sétend dans le sens de la largeur (W) et qui est positionnée plus vers larrière que la première partie incurvée (41).
