Abstract
An objective is to provide an absorbent article that can prevent backflow and can reduce water retention in a front sheet as much as possible. In an incontinence padfor use with a medium or larger volume that absorbs 20 cc or a larger volume of urine, a front sheetis formed by coating a water repellent on a spunlace nonwoven fabric that is made of 100 wt. % of cotton fiber. On a skin facing surface side, in a plan view, recess part linesof a diamond-shaped lattice pattern are formed from many first recess part linesthat go along a predetermined inclination angle direction and are formed with a constant gap in the pad longitudinal direction and many second recess part linesthat go along the inclination angle direction obtained by reversing the first recess part linesin a width direction by the pad longitudinal direction and are formed with a constant gap in the pad longitudinal direction, partition areasof a diamond-shaped lattice shape partitioned by these recess part linesare arranged adjacently in the longitudinal direction and the width direction. Furthermore, many open holespenetrating through both sides are formed at least at an excretion hole corresponding part H.
