Abstract
An absorbent article includes a compressed groove provided on a body-side surface of a sanitary napkin includes a pair of lateral groove segments extending substantially in the longitudinal direction symmetrically about a longitudinal center line and a pair of rear groove segments converging rearward from respective rear ends of the pair of lateral groove segments so that the compressed groove as a whole presents an elongated shape which is angular rearward. The rear side groove segment has a curve conforming, in the vicinity of its rear end, with an arc of a circle having a predetermined radius and inscribed to the rear side groove segment. A bottom covering region extending rearward from the rear end of the rear groove segment has a predetermined thickness and is adapted to be folded along the longitudinal center line so that the bottom covering region can become convex on the side of the body-side surface. A distance between a pair of proximal ends of the rear side groove segment as measured in the transverse direction is in a predetermined range and a distance from the pair of proximal ends to the rear end of the rear groove segment as measured in the longitudinal direction is in a predetermined range.
