    • PROBLEM TO BE SOLVED: To provide a dispersion reinforced copper which has carbides dispersed in the matrix, and has superior tensile strength, elongation and electroconductivity; a manufacturing method therefor; a drawn wire material made from the dispersion reinforced copper; and a wire harness with the use of the drawn wire material as a conductor, for automobiles.
      SOLUTION: The dispersion reinforced copper having fine carbides dispersed in the matrix formed from Cu or a Cu alloy is obtained by the steps of: heating a molten metal mixture of pure Cu or the Cu alloy, a carbide-forming element like Ti, and a carbon source like an Fe-C alloy to a melting point of the carbon source or higher; thereby making the carbide-forming element react with C in the carbon source to produce a carbide; stirring the molten metal to uniformly disperse the carbide in the molten metal; and solidifying the molten metal at a cooling rate of 100°C/sec or higher. The drawn wire material made from the dispersion reinforced copper can be preferably used as a conductor for an electric wire of a wire harness for automobiles.
