The non-woven fabric has points connected by the thermal fusion, formed by intersections bound by thermal fusion of constituent fibers. The conjugated fiber of core/shell comprises a heat extensible fiber which length is increased by heating, and the heat extensible fiber has a hydrophilicity gradient in the thickness direction and/or in the planar direction of the non-woven fabric (10).
