Provided is an absorbent article in which the occurrence of wrinkles can be suppressed and the degradation of fitting property and absorption performance can be suppressed. This absorbent article is provided with an absorbent main body (10) including an abdomen-side section (2), a backside section (3), and an absorbent body (14). The absorbent body has a squeeze section (71) that includes a highly absorbent polymer and extends in the longitudinal direction. The absorbent main body includes, on both sides in the width direction, one pair of side sheets (17, 17) extending in the longitudinal direction. The side sheets each have: fixed regions (15, 15) that are positioned on an end section on the front side and rear side in the longitudinal direction and fixed to a surface of the absorbent main body； and a leak preventing wall (16) which includes an elastic member (61) extending in the longitudinal direction, is positioned between the fixed regions on the front side and the rear side, fixes the outer end edge in the width direction to the surface of the absorbent main body, and does not fix the inner end edge in the width direction. In the longitudinal direction, an end edge (71e) on the front side of the squeeze section is positioned closer to the front side in the leak preventing wall than the front end edge, and an end edge (71e) on the rear side of the squeeze section is positioned closer to the rear side in the leak preventing wall than the rear end edge.L'invention concerne un article absorbant dans lequel l'apparition de plis peut être supprimée et la dégradation de la propriété d'ajustement et de la performance d'absorption peut être supprimée. Cet article absorbant est pourvu d'un corps principal absorbant (10) comprenant une section côté abdomen (2), une section arrière (3), et un corps absorbant (14). Le corps absorbant a une section de compression (71) qui comprend un polymère hautement absorbant et s'étend dans la direction longitudinale. Le corps principa
