An electric insulated wire according to the present invention is formed by applying a first insulation coating made from polyimide resin having a repeating unit represented as in chemical formula (1) to an electric conductor directly or through an insulation layer made from a second insulation coating, after which the first insulation coating is baked, the polyimide resin including a quadrivalent aromatic group (X) having an aromatic ether structure, a bivalent aromatic group (Y 1 ) having an aromatic ether structure, and a bivalent aromatic group (Y 2 ) having a fluorene structure; the first insulation coating has a compound ratio (Y 1 /Y 2 ) of the bivalent aromatic group having an aromatic ether structure to the bivalent aromatic group having a fluorene structure within a range from 30/70 to 80/20, when represented as a mole ratio. |
