Abstract:
1. An elongated absorbent article having a skin surface and a garment surface, comprising a liquid-permeable topsheet appearing on the skin surface, a backsheet appearing on the garment surface, and a liquid absorbent layer disposed between the topsheet and the backsheet, wherein compressed grooves where the liquid absorbent layer is compressed together with the topsheet are disposed to extend symmetrically about a longitudinal centerline of the absorbent article, defining therebetween an elongated central region, the central region including a front portion and a rear portion, wherein in the central region, a nonwoven fabric forming the topsheet is formed with liquid passage holes passing through at least the topsheet and dot-embossments where at least the topsheet is compressed, wherein aperture density obtained by dividing (total of areas occupied by the liquid passage holes in the front portion) by (area of the front portion) is higher than aperture density obtained by dividing (total of areas occupied by the liquid passage holes in the rear portion) by (area of the rear portion), while embossment density obtained by dividing (total of areas occupied by the embossments in the rear portion) by (area of the rear portion) is higher than embossment density obtained by dividing (total of areas occupied by the embossments in the front portion) by (area of the front portion).
