Abstract:
A insulated wire includes a conductor, and an insulating coating on a periphery of the conductor. The insulating coating includes an insulating film formed by applying and baking a polyester imide resin insulating coating material, and the insulating film has a relative permittivity of less than 3.5 both in a dried state and in a moisture-absorbed state. The insulating film is formed by applying and baking a polyester imide resin insulating coating material including an imide dicarboxylic acid and an alcohol component, the imide dicarboxylic acid being obtained by synthesizing a diamine component including aromatic diamine having not less than three aromatic rings and an acid component including aromatic tricarboxylic acid anhydride.
