Abstract
An absorbent article that prevents back flow and that uses cotton fibers in the surface sheet. The absorbent article is an incontinence pad having at least a medium volume for absorbing at least 20 cc of urine. A surface sheet is formed by coating, with a water-repellent, a spunlace non-woven fabric comprising 100 wt % of cotton fibers. The skin-facing surface side is provided with: a plurality of protrusions that extend along the longitudinal direction of the incontinence pad and are formed with gaps therebetween in the widthwise direction; and a plurality of recesses that extend along the longitudinal direction of the incontinence pad and are formed between adjacent protrusions. The recesses are formed thinner than the protrusions. A plurality of openings, which penetrate the incontinence pad from the front to the rear thereof, is formed along the recesses in at least a section (H) corresponding to an excretory opening.
