Abstract
An incontinence pad includes an absorbent body provided between a liquid permeable topsheet and a backsheet, a concave groove formed in a surface of the absorbent body on the liquid permeable topsheet side and extending along an approximately longitudinal direction of the groove, and a highly compressed portion formed in a bottom surface of the concave groove. The highly compressed portion includes a sloping element in a unit portion formed by dividing the concave groove 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.
