Abstract
There is disclosed an insulated wire, having, on a conductor, an insulating coating including at least three layers, made up of an underlayer formed by applying and baking a polyamine-imide-series resin coating material, containing 0.05 to 1.0 parts by weight of a trialkylamine, and/or 5 to 20 parts by weight of an alkoxylated melamine resin, per 100 parts by weight of a polyamide-imide-series resin, an intermediate layer formed by applying and baking a polyimide-series resin coating material, and an overlayer formed by applying and baking a self-lubricating-type polyamide-imide-series resin coating material. According to the insulated wire, an insulating coating can be prevented from being damaged at the time of the working of a coil under severe conditions, even when the insulating coating is thin.
