Provided is an absorbent article which makes it easy to fold wing sections of the absorbent article so as to match the shape of the edges of the leg openings of underwear. The present invention is an absorbent article (1) having a lengthwise direction (Y-direction) and a widthwise direction (X-direction), and including: a body section (10) provided with a liquid-permeable top sheet (2) on the skin-side, a liquid-impermeable backsheet on the garment-side, and a liquid-holding absorbent body (4) positioned between the top sheet (2) and the backsheet and wing sections (5) extending so as to project in the widthwise direction from both side-edges of the body section (10). Therein, the surface opposite the garment-side surface in the wing sections (5) is configured from the top sheet (2) or from side sheets positioned on both sides in the widthwise direction of the top sheet (2). Furthermore, the surface opposite the garment-side surface in at least the wing sections (5) of the top sheet (2) or the side sheets includes a plurality of bending parts (21) extending non-continuously in the lengthwise direction, arranged in the widthwise direction, and having a cross-sectional shape in the widthwise direction that is substantially U-shaped.
