Non-woven fabric and method for producing same

The present invention addresses the problem of providing a non-woven fabric that is fluffy, has excellent flexibility, and has high strength. A non-woven fabric in which the intersections of thermally fusible composite fibers are thermally fused, the non-woven fabric being characterized in that the fiber density of a high-density-side surface layer of the non-woven fabric is 5/mm2 to 20/mm2, and the ratio of the fiber density of the high-density-side surface layer to the fiber density of a low-density-side surface layer of the non-woven fabric is 1.4 or less. The strength per unit area weight of the non-woven fabric is 0.40 N/50 mm or more. 本发明的课题在于提供一种蓬松且柔软性优异、强度高的无纺布。一种无纺布，热熔接性复合纤维的交点被热熔接，所述无纺布中，所述无纺布的高密度侧表层的纤维密度为5根/mm2～20根/mm2，所述无纺布中的高密度侧表层的纤维密度与低密度侧表层的纤维密度之比为1.4以下，所述无纺布的每单位面积重量的强度为0.40N/50mm以上。
