PROBLEM In an absorbent article including a concave groove formed in an upper surface along a longitudinal direction, a deformation of the concave groove when being worn is prevented, and a body fluid is made easy to distribute in the longitudinal direction of the groove. PROBLEM TO BE SOLVED There is provided an incontinence pad including an absorbent body (4) provided between a liquid permeable topsheet (3) and a backsheet (5), a concave groove (22) formed in a surface of the absorbent body (4) on the liquid permeable topsheet (3) side and extending along an approximately longitudinal direction of the groove, and a highly compressed portion (23) formed in a bottom surface of the concave groove (22). The highly compressed portion (23) includes a slanted element (25) in a unit portion (24) formed by dividing the concave groove (22) in a longitudinal direction thereof and crossing the concave groove from one side edge to the other side edge, and is formed into a pattern obtained by repeatedly inverting the highly compressed portion of the unit portion in the longitudinal direction.
