A non-woven fabric comprising thermally fusible composite fibers with shortened heat-sealing time and improved heat-sealing strength is provided. The non-woven fabric is produced using side-by-side type or sheath-and-core type thermally fusible composite fibers comprising a first component consisting of polyethylene and a second component consisting of polyester, said polyethylene Occupying continuously at least a portion of the surface of the fiber in the length direction, wherein said polyethylene is a copolymer having 1.6/1,000 C or more methyl branches in its molecular chains, a density from 0.940 to 0.965 g/cm3, and a Q value (weight average molecular weight Mw/number average molecular weight Mn) of 4.8 or less. |
