Abstract

There is provided an absorbent article with its front-surface sheet composed of cotton fibers by which liquid reversion is prevented and water retention on the front-surface sheet is minimized. An incontinence padis provided that is configured to absorb urine at medium or more volume that is 20 cc or more. A front-surface sheetis formed of a spunlace nonwoven fabric 100 wt % of which is composed of cotton fibers and which is coated with a water repellent agent, and has, at least at a portion corresponding to an excreting hole, numerous front-face/back-face penetrating openingsthat are longer shaped in the longitudinal direction of the incontinence pad. The cotton fibers form numerous longitudinal streaksand numerous lateral streaks, the longitudinal streaks extending along the longitudinal direction of the incontinence padand being formed with an interval in the width direction of the incontinence pad, and the lateral streaks extending along the width direction of the incontinence padand connecting together the longitudinal streaks formed with an interval in the longitudinal direction of the incontinence pad. The openingsare formed within portions surrounded by the longitudinal streaksand the lateral streaks. The longitudinal streakshave more fibers and are formed at a higher density than the lateral streaks
