PROBLEM TO BE SOLVED: To provide an insulated wire that has such excellent processing resistance as to sufficiently sustain severe processing stress and is remarkably excellent in heat resistance and resistance to thermal degradation.SOLUTION: The insulated wire has on a conductor 10 an insulation film 20 consisting of a first layer 21 composed of a first polyamide imide containing an adhesion improver, a second layer 22 composed of a second polyamide imide produced by reacting an isocyanate component containing 10-70 mol% of the total of 2,4'-diphenylmethane diisocyanate and a dimer acid diisocyanate with an acid component formed on the first layer 21 and a third layer 23 composed of a polyimide formed on the second layer 22. |
