1. A method for manufacturing an electric wire comprising a conductor, the method comprising:

  • providing wire rods made of aluminum alloy, a composition of the aluminum alloy containing 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;

    forming aluminum alloy wires by drawing the wire rods to a final wire diameter without heat treatment; and

    forming the conductor by twisting the aluminum alloy wires together with a twist pitch of 7 to 36 times a predetermined diameter of the conductor.
