ABSTRACT:
The present invention relates to an insulated wire comprising a conductor and at least two insulating layers provided on the outer periphery of the conductor. The inner insulating layer is provided directly or via another insulation on the outer periphery of the conductor and comprises a polyolefin compound containing 20 to 80 parts by weight of at least one substance selected from ethylene .alpha.-olefin copolymer, ethylene .alpha.-olefin polyene copolymer (.alpha.-olefin having the carbon numbers of C.sub.3 -C.sub.10, polyene being non-conjugated diene). The outer insulating layer is made primarily of a heat resistant resin which contains no halogen and which is a single substance or a blend of two or more substances selected from polyamide, polyphenylene sulfide, polybutylene terephthalate, polyethylene terephthalate, polyether ketone, polyether ether ketone, polyphenylene oxide, polycarbonate, polysulfone, polyether sulfon, polyether imide, polyarylate, polyamide, or a polymer alloy containing such resin as the main component.
