Abstract
A conductor of an electric wire, and an insulated wire which are excellent in corrosion resistance and recyclability, of which the strength which is decreased by weight reduction and diameter reduction is improved. The conductor includes a strand which includes a first elemental wire made from pure copper and a second elemental wire made from a copper alloy. In the conductor, a cross-sectional area of the first elemental wire as a percentage of a cross-sectional area of the conductor is preferably within a range of 10 to 90%. Examples of the copper alloy include a Cu—Ni—Si alloy, and a copper alloy containing Sn, Ag, Mg, or Zn. The conductor may be compressed concentrically. The insulated wire is prepared by covering the conductor with an insulator.
