Disclosed is a nonwoven fabric which comprises heat-fusible composite fibers consisting of a first resin component and a second resin component that has a higher melting point than the first resin component, wherein a contact site of the heat-fusible composite fibers is fused to form a fiber-fusion site. The aforesaid nonwoven fabric has a first surface, wherein said heat-fusible composite fibers are fixed in parallel, and a second surface and, in the first surface, the percentage of the number of sites at which fibers are fixed in parallel to the total number of the aforesaid fiber-fusion sites is 5-30%. It is preferred that said percentage in the first surface exceeds the percentage in the second surface.本發明之不織布係包含含有第1樹脂成分及熔點高於第1樹脂成分之第2樹脂成分之熱熔接性複合纖維,且上述熱熔接性複合纖維彼此接觸之部分熔接而形成纖維熔接部者,該不織布包含具有上述熱熔接性複合纖維以並行狀態固定化之部位之第1面及第2面,第1面中纖維以並行狀態固定化之部位之個數相對於上述纖維熔接部之個數之比例(百分率)為5~30%。較佳為第1面之上述比例(百分率)大於第2面。L1‧‧‧纖維之熔接部分之長度P1‧‧‧纖維之熔接部分之粗度
