Abstract
To provide an absorbent article that uses a cotton fiber in a front-surface sheet, prevents rebounding, improves an absorption speed, and reduces a diffusion range of urine in the front-surface sheet. An incontinence padhaving a medium or larger volume that absorbs 20 cc or a larger volume of urine is provided. A front-surface sheetis a spunlace nonwoven fabric made of 100% cotton fiber by weight, is coated with a water repellent agent and has many front-face/back-face penetrating openingsin a region containing a part corresponding to an excreting hole. The absorber is made of a pulp fiber that does not contain synthetic fiber and a superabsorbent polymer, a basis weight of the pulp fiber being 75 to 300 g/m, a basis weight of the superabsorbent polymer being 85 to 185 g/m, and a ratio of the pulp fiber and the superabsorbent polymer being pulp fiber:superabsorbent polymer=70 to 30% by weight:30 to 70% by weight.
