A high-speed transmission cable conductor, comprising:
- a core material comprising mainly copper;
- and
- a surface treated layer formed around a surface of the core material, the surface treated layer comprising an amorphous layer including a metal element having a higher affinity for oxygen than the copper, and oxygen.
A high-speed transmission cable conductor producing method, comprising:
- forming a coating layer comprising a metal element having a higher affinity for oxygen than copper around a surface of a core material comprising mainly copper;
- and
- heat treating the coating layer at a temperature of not less than 50 degrees Celsius and not more than 150 degrees Celsius, and for a time period of not less than 30 seconds and not more than 60 minutes, to thereby form a surface treated layer.
