PROBLEM TO BE SOLVED: To provide an insulation wire of which melting deformation of an insulation coating is inhibited even when the insulation coating is exposed to a temperature more than the melting point of a resin composition consisting the insulation coating.SOLUTION: There is provided an insulation wire containing a conductor and an insulation wire formed to coat circumference of the conductor, where the insulation coating is formed from a resin composition, the resin composition contains (A) a polyphenylene sulfide resin having a carboxyl group at its terminal and (B) an olefin copolymer containing α olefin (b1) and unsaturated acid glycidyl ester having an epoxy group which addition reacts to the carboxyl group which the polyphenylene sulfide resin (A) has (b2) with the maass ratio of the unsaturated acid glycidyl ester (b2) of 0.5 mass% to 40 mass%, and having a phase separation structure which the dispersion phase containing the olefin copolymer (B) is dispersed in a continuous phase containing the polyphenylene sulfide resin (A) and viscoelasticity of the resin composition at 300°C of 5.0×10Pa s or more. |
