Provided is an insulated electrical wire having an insulating coating that is relatively inexpensive, has good mechanical strengths such as hardness and good thermosoftening resistance, and exhibits a high corona discharge inception voltage. The insulated electrical wire comprises a conductor and an insulating coating which covers the conductor, and the insulating coating includes an insulating layer formed by applying and baking a mixed resin of a polyetherimide and a polyesterimide. In particular, the mixing ratio (weight ratio) of the polyesterimide to the polyetherimide is 75:25 to 10:90. An electrical coil produced by winding the insulated electrical wire and a motor comprising the electrical coil are also provided. |
