An absorbent article having an absorber interposed between a front sheet and a back sheet , characterized in that the absorbent article is an incontinence pad that is capable of absorbing 20 cc or more of urine; the front sheet is formed by coating a water repellent on a spunlace nonwoven fabric made of 100 wt.% of cotton fiber and, on a skin facing surface side thereof, in a plan view, recess part lines of a diamond-shaped lattice pattern are formed from many first recess part lines that go along a predetermined inclination angle direction and are formed with a constant gap in the longitudinal direction of the absorbent article and many second recess part lines that go along an inclination angle direction obtained by reversing the first recess part lines in a width direction by a longitudinal direction line of the absorbent article and are formed with a constant gap in the longitudinal direction of the absorbent article , partition areas of a diamond-shaped lattice shape partitioned by these recess part lines are arranged adjacently in the longitudinal direction and the width direction of the absorbent article , and many open holes penetrating through two sides are formed at least at an excretion hole corresponding part (H); and on the absorber side of the front sheet , a second sheet made of a thermoplastic fiber is adhered thereto, and at the same time, the front sheet and the second sheet are bonded at the first recess part lines and second recess part lines by heat sealing of the second sheet , basis weights of the recess part lines and the basis weight of the partition area are formed at a substantially equal level, and the density of the recess part lines is formed higher than the density of the partition area . the absorbent article is an incontinence pad that is capable of absorbing 20 cc or more of urine; the front sheet is formed by coating a water repellent on a spunlace nonwoven fabric made of 100 wt.% of cotton fiber and, on a skin facing surface side thereof, in a plan view, recess part lines of a diamond-shaped lattice pattern are formed from many first recess part lines that go along a predetermined inclination angle direction and are formed with a constant gap in the longitudinal direction of the absorbent article and many second recess part lines that go along an inclination angle direction obtained by reversing the first recess part lines in a width direction by a longitudinal direction line of the absorbent article and are formed with a constant gap in the longitudinal direction of the absorbent article , partition areas of a diamond-shaped lattice shape partitioned by these recess part lines are arranged adjacently in the longitudinal direction and the width direction of the absorbent article , and many open holes penetrating through two sides are formed at least at an excretion hole corresponding part (H); and on the absorber side of the front sheet , a second sheet made of a thermoplastic fiber is adhered thereto, and at the same time, the front sheet and the second sheet are bonded at the first recess part lines and second recess part lines by heat sealing of the second sheet , basis weights of the recess part lines and the basis weight of the partition area are formed at a substantially equal level, and the density of the recess part lines is formed higher than the density of the partition area . <EOS>
