Abstract
An absorbent article including an absorbent layer and a liquid-permeable surface sheet placed on a liquid-receiving side of the absorbent layer for introducing excreted liquid from the human body to the absorbent layer. The surface sheet is of a corrugated configuration to have valleys and peaks extending in a longitudinal direction of the article and alternately arranged in a transverse direction perpendicular to the longitudinal direction. Each peak is formed with spares parts and dense parts alternately arranged in the longitudinal direction. The surface sheet has a lower fiber density in the sparse parts than in the dense parts.
