There is provided an insulated wire having an insulation film composed of a plurality of layers provided on a conductor, in which: the insulation film includes a first film layer and a second film layer; the first film layer is made of a first resin composition formed by graft-polymerizing a graft compound with an ethylene-tetrafluoroethylene copolymer and is provided on a circumference of the conductor; and the second film layer is made of a second resin composition being a polymer alloy made of a polyphenylene sulfide resin and a polyamide resin, or being a polymer alloy made of a polyether ether ketone resin and a polyamide resin and is provided on a circumference of the first film layer.

Insulated wire

An insulated electric wire is composed of a conductor, and a lubricating layer containing a lubricant. The lubricating layer is formed around the perimeter of the conductor. The lubricating layer is not less than 0.06 and not more than 0.12 in an absorbance ratio A/Aexpressed by an absorbance Aof carbon-hydrogen stretching vibration and an absorbance Aof benzene ring framework vibration, obtained by Fourier Transform Infrared Spectroscopy analysis of a surface of the lubricating layer.
