Abstract
In a self-bondable insulated wire comprising a conductor and three resin insulating layers, the first resin insulating layer is formed with a resin selected from the group consisting of polyimide resins, polyamideimide resins and polyesterimide resins, the intermediate resin insulating layer is formed with a resin selected from the group consisting of polyvinyl formal resins and epoxy resins, and the outermost resin insulating layer is formed with a self-bondable resin of phenoxy series. Thus, a self-bondable insulated wire which is excellent in both oil resistance and heat resistance is obtained.
