Abstract: An electric wire uses a thermoplastic fluororesin composition as an insulating layer covering a periphery of a conductor. The thermoplastic fluororesin composition includes a fluororubber, a fluororesin and a compatibilizer. The fluororesin includes a first fluororesin constituted by perfluoroalkoxy alkane having a melting point of 280° C. or more and 290° C. or less, and the compatibilizer is a terpolymer of tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride. A weight ratio (%) of the fluororubber to the fluororesin ranges from 20:80 to 60:40, and the fluororubbers are crosslinked to one another by dynamic crosslinking.
