Abstract:
An absorbent article (1) includes a hip hold portion (H) and a main body (8) including a liquid-pervious topsheet (3), a liquid-impervious backsheet (2), and an absorbent member (4) arranged between the topsheet and the backsheet. The main body has a shape with a prescribed length in the front-back direction and a prescribed width in the direction orthogonal to the front-back direction. The hip hold portion includes a side region (10) protruding from a backward side portion of the main body, and the side region includes a first protrusion (41) including a portion having a greatest width from a front-back direction centerline of the main body, a first recess (51) that is in front of and adjacent to the first protrusion, and a second protrusion (42) that is in front of and adjacent to the first recess. The outline of the first recess includes a curved line, and a rigid area (70) including one or more rigid portions (60) with enhanced rigidity is provided on a first imaginary line passing through a bottom point of the first recess and a center of a circle of curvature of a curve at the bottom point of the first recess.
