Abstract: According to one embodiment, an insulated wire is disclosed. The insulated wire includes an aluminum conductor, and a first insulating film provided on the aluminum conductor. The first insulating film is made of a first polyimide obtained by reacting an acid component containing 50 mol % to 90 mol % of 3,3?,4,4?-biphenyl tetracarboxylic acid dianhydride, 5 mol % to 20 mol % of 3,3?,4,4?-benzophenone tetracarboxylic acid dianhydride, and 5 mol % to 40 mol % of pyromellitic anhydride with a diamine component containing 4,4?-diaminodiphenyl ether.

Abstract: According to one embodiment, an insulated wire is disclosed. The wire includes a conductor and an insulating film formed on the conductor, the insulating film including a first layer of a first polyamideimide containing an adhesion improver; a second layer of a second polyamideimide obtained by reacting an isocyanate component containing 10 to 70 mol % in total of 2,4?-diphenylmethane diisocyanate and dimer acid diisocyanate with an acid component; and a third layer of a polyimide obtained by reacting an acid component containing 50 to 80 mol % of 3,3?,4,4?-biphenyl tetracarboxylic dianhydride and 20 to 50 mol % of pyromellitic anhydride with a diamine component containing 4,4?-diaminodiphenyl ether.
