ABSTRACT:
An absorbent core 4 composed of a nonwoven fabric containing an absorbent fiber at 20% by weight or more to 80% by weight or less and a hydrophobic fiber at 20% by weight or more to 80% by weight or less is interposed between a top sheet 3 and a bottom sheet 5, both the sheets being composed of a nonwoven fabric containing an absorbent fiber, such as rayon, at 30% by weight or more to 70% by weight or less and a hydrophobic fiber at 30% by weight or more to 70% by weight or less. Then, the top sheet 3, the absorbent core 4 and the bottom sheet 5 are bonded together on bonding lines 2. These individual layers are water retentive because of the absorbent fiber therein, and the resulting sheet has good slip properties because of the hydrophobic fiber contained therein. The absorbent core 4 works to enhance the bending resistance.
