PROBLEM TO BE SOLVED: To provide a conjugated fiber that has flexibility, spinnability (drafting properties), a moderate level of heat resistance and unstickiness, provide a method for producing the same and provide nonwoven fabric using the conjugated fiber. SOLUTION: As one component of the conjugated fiber, is used (A) a resin material including a ethylene (co)polymer that satisfies the following: (a) a density of 0.86 to 0.97 g/cm<SP>3</SP>, (b) a melt flow rate of 2 to 200 g/10 min, (c) a molecular weight distribution (Mw/Mn) of 1.5 to 4.5, (d) the difference between T<SB>25</SB>and T<SB>75</SB>obtained from the integrated elution curve of the elution temperature - elution volume curve according to TREF and density d satisfies the relation: T<SB>75</SB>-T<SB>25</SB>≤-670×d+644.
