Abstract: An absorbent article is improved to restrict a possibility that through-hole(s) formed in a separate sheet might have width dimension(s) narrowed as the separate sheet is spaced from a liquid-absorbent structure. The absorbent includes first front and rear elasticized regions outside of opposite lateral regions as viewed in a transverse direction of the separate sheet. Each of these first front and rear elasticized regions is paired and spaced apart from each other in the transverse direction and between respective pairs of first front and rear elasticized regions. Front and rear non-elasticized regions are free from any influence by the contractile force of the front and rear waist elastic members. The sub-regions of the front and rear waist regions unoccupied by a liquid-absorbent structure extend in the transverse direction between respective pairs of opposite side edges.
