Abstract:

An absorbent core (40) that constitutes this absorber (4) includes fiber masses (11) and absorbent fibers (12F). The fiber masses (11) include low-water absorptive fibers (11F) which have a water absorptivity that is lower than that of the absorbent fibers (12F). The fiber masses (11) are entangled with each other or with the absorbent fibers (12F). Each fiber mass (11) has two basic surfaces (111) that face each other and a skeletal surface that connects the two basic surfaces (111).
