Abstract
Disclosed is an absorbent article including: a liquid permeable surface layer formed of continuous filaments individually extending over the entire length of the surface layer, the continuous filaments including at least heat-fusible continuous filaments; a backing sheet; and a fibrous absorbent core located between the surface layer and the backing sheet and containing heat-fusible fibers. Between the surface layer and the fibrous absorbent core, disposed is an absorbent sheet which is formed of superabsorbent polymer to have a plurality of through passages. The surface layer and the fibrous absorbent core are partially fusion-bonded to each other via the through passages formed in the absorbent sheet for retaining the absorbent sheet between the surface layer and the fibrous absorbent core.
