Composite electric cable and process for producing same

A method for producing a composite electric cable, the method comprising:

• a step (a) of mixing an elastomer, aluminum material particles, and carbon nanotubes, to thereby prepare a mixture;
• a step (b) of heating the mixture so as to vaporize and decompose the elastomer, to thereby prepare a raw material;
• a step (c) of sintering the raw material, to thereby form a billet;
• a step (d) of drawing the billet through a die, to thereby form a carbon-nanotube-containing aluminum element wire made of a composite material;
• and
• a step (e) of twisting together element wires including the carbon-nanotube-containing aluminum element wire.
