PROBLEM TO BE SOLVED: To provide an insulated wire with higher partial discharge starting voltage as compared with a prior art in a wide temperature range, while securing adhesiveness between a conductor and an insulation coating equivalent to a conventional technology.SOLUTION: The insulated wire is provided with an insulation coating formed on a conductor. The insulation coating has at least two layers of a first insulation coating layer formed directly on the conductor and a second insulation coating layer formed outside the first insulation coating layer. The first insulation coating layer is composed of a resin composition in which a resin (A) consisting of polyphenylene sulfide and a resin (B) consisting of polyamide are mixed with a ratio of parts by mass in a range of "30/70≤B/A≤90/10", and the second insulation coating layer is composed of a resin composition containing a resin (C) consisting of polyphenylene sulfide or polyether ether ketone as a main component. |
