INSULATED CONDUCTOR AND METHOD FOR MANUFACTURING SAME
An insulated conductor includes a conductor, and an insulation covering the conductor and formed of a resin composition. The resin composition includes more than 60% by weight of polybutylene naphthalate resin. The resin composition further includes a hydrogenated block copolymer that a block copolymer including a styrene and a diene system compound is saturated by hydrogenation, and at least one of a polyolefin and a compound including a glycidyl group. A method for manufacturing the insulated conductor includes forming on the conductor the insulation including the resin composition by extrusion in a range of 290° C. to 310° C.
