Abstract
The absorbent article is sequentially provided with a surface sheet (1) facing the skin, allowing excremental liquid to permeate through it and constructed from a perforated sheet, a permeation sheet (2) allowing the excremental liquid to permeate through it, and an absorbent element (3) located on the rear surface side of the permeation sheet (2) and containing cotton-like pulp for holding the excremental liquid. Soft feces permeation speed S1 of the surface sheet (1) is higher than soft feces permeation speed S2 of the permeation sheet (2). Permeation apertures for excremental liquid are formed at least that portion of the apertured surface sheet (1) which faces an excretion section for receiving the excremental liquid and also formed at an excretion region including the portion. In the permeation apertures, an effective opening area of a single permeation aperture (H) is 3-75 mm2 and an opening area ratio is 10-80%. Further, a cotton-like pulp layer of the absorbent element (3) is exposed to the use surface side, and the absorbent element (3) is directly adjacent to and between the surface sheet (1), the permeation sheet (2), and the cotton-like pulp layer.
