PURPOSE:To provide an insulated wire exhibiting excellent lubricity even when film thickness is thin, by coating the outermost layer with a paint containing, as a main component, a polyester resin in which at least one terminal group of the molecule is a straight-chain alkyl group having a specified number of carbon atoms, followed by baking. CONSTITUTION:In an insulated wire obtd. by coating with an insulating paint directly or through an insulation on a conductor and baking it, at least the outermost layer is coated with a paint containing, as a main component, a polyester resin in which at least one terminal group of the molecule is a 21C or higher straight-chain alkyl group, and then baked. An insulated wire having excellent lubricity can be obtd. An example of said polyester resin is a resin obtd. by reacting a polyhydric alcohol (A) such as ethylene glycol, a polycarboxylic acid or anhydride (B) such as terephthalic acid and a compd. (C) having a 21C or higher straight-chain alkyl group and a functional group capable of reacting with component A or B such as methyl behenate. |
