Abstract: A method of manufacturing an electric wire includes providing wire rods made of aluminum alloy, forming aluminum alloy wires by drawing the wire rods to a final wire diameter without heat treatment, and forming a conductor by twisting together the aluminum alloy wires with a twist pitch of 7 to 36 times a predetermined diameter of the conductor. A composition of the aluminum alloy contains 0.1 to less than 1.0% by weight of Fe, 0 to 0.08% by weight of Zr, 0.02 to 2.8% by weight of Si, and 0.05 to 0.63% by weight of Cu and/or 0.03 to 0.45% by weight of Mg, with the remainder being Al and unavoidable impurities.
