Zusammenfassung:	PURPOSE:To produce an electrically conductive wire suitable as power transmission lines, lead wires, etc., in a state of excellent work efficiency and safety by coating the surface of a nonferrous metal with a lubricating oil of a specific composition and subjecting the coated metal to plastic working using a die. CONSTITUTION:The surface of a nonferrous metal is coated with a lubricating oil prepared by blending a liquid polymer compound having preferably 300-50000cSt viscosity (at 40 deg.C) as a base oil with an additive consisting of animal or vegetable fats and oils and/or an aliphatic dicarboxylic acid. The resultant coated metal is then subjected to diameter reduction working using preferably a drawing die for draw working wires and then wire drawing working while forming a lubricating film with heat generated therefrom to produce the objective electrically conductive wire.
