INSULATED WIRE |
| 摘要 |
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. |
