Abstract
Disclosed is an absorbent article including a sheet which is composed of: a resin layer having a plurality of apertures and forming a liquid-receiving face of the sheet; and a fibrous layer underlying the resin layer. The fibrous layer contains hydrophobic fibers and hydrophilic fibers shorter than the hydrophobic fibers. At least a part of the hydrophilic fibers form aggregates that disperse in the fibrous layer, and at least a part of the aggregates are bonded to the surfaces of the hydrophobic fibers.
