ABSTRACT:
The present invention aims at providing a non-woven fabric having high-density regions and low-density regions dispersed horizontally, so as not to prevent liquid transfer from a surface sheet to an absorbent body and not to diffuse a liquid less during transfer, a manufacturing method thereof, and a disposable diaper made therefrom. The non-woven fabric5includes a plurality of high-density regions11and a plurality of low-density regions12dispersedly formed in a planar direction thereof. The high-density regions11are formed dominantly on at least one side of the non-woven fabric5, and the low-density regions12are formed communicating both sides thereof.
