Insulated wire
An insulated wire includes a conductor, and an insulating covering layer formed on a periphery of the conductor and including two or more insulating coatings. The insulating coatings include a polyamide-imide resin insulating material represented by chemical formula 1:where R indicates a divalent aromatic diamine including three or more aromatic rings. The insulating coatings are formed by applying and baking the polyamide-imide resin insulating material, and the polyamide-imide resin insulating material is obtained by reacting an imide group containing dicarboxylic acid with a diisocyanate, the imide group containing dicarboxylic acid being obtained by dehydration reaction of a diamine comprising a divalent aromatic diamine including three or more aromatic rings with an acid using an azeotropic solvent.
