High-speed transmission cable conductor, and producing method thereof, and high-speed transmission cable

摘要

A high-speed transmission cable conductor includes a core material includes mainly copper, and a surface treated layer formed around a surface of the core material. The surface treated layer includes an amorphous layer including a metal element having a higher affinity for oxygen than the copper, and oxygen.

1. A high-speed transmission coaxial cable, comprising:
an inner conductor; an insulator provided around an outer periphery of the inner conductor; an outer conductor provided around an outer periphery of the insulator; and a sheath provided around an outer periphery of the outer conductor, wherein the inner conductor comprises:
a core material comprising mainly copper, anda surface treated layer formed around a surface of the core material, the surface treated layer comprising an amorphous layer consisting essentially of a metal element, oxygen and copper, the metal element having a higher affinity for oxygen than the copper included in the amorphous layer,wherein the copper is diffused from the core material, and the metal element and the oxygen of the amorphous layer are predominantly bonded together.
