PROBLEM TO BE SOLVED: To provide a multifilament that has excellent flexibility, spinnability (drafting properties) and unstickiness and provide a method for easily producing such a multifilament. SOLUTION: The multifilament is made of a resin material comprising (A) an ethylene (co)polymer satisfying the followings: (a) a density of 0.88-0.97 g/cm<SP>3</SP>, (b) a melt flow of 0.5-200 g/10 min, (c) molecular weight distribution (Mw/Mn) of 1.5-4.5, (d) the difference between T<SB>25</SB>and T<SB>75</SB>obtained from an integral elusion curve according to an elution curve of elusion temperature-elusion volume according to TREF and the density (d) satisfy T<SB>75</SB>-T<SB>25</SB>≤-670×d+644. The multifilament is produced by melt-spinning this resin material and drawing the melt spun yarn. COPYRIGHT: (C)2005,JPO&NCIPI
