Abstract
Disclosed is an absorbent article including a topsheet, a backsheet and an absorbent core positioned between the topsheet and the backsheet, and having leakage-preventing side walls on a liquid-receiving side of the article. The leakage-preventing side walls extend in a longitudinal direction of the article and lie opposite one another in a width direction of the article. At least a liquid-receiving face of each leakage-preventing side wall is made of a fibrous sheet that contains hydrophobic fibers thermally bonded to one another and hydrophilic fibers shorter than the hydrophobic fibers. At least a part of the hydrophilic fibers form aggregates which are dispersed in the fibrous sheet and are bonded to the hydrophobic fibers.
