Abstract

A cable wire having a core conductor 11, an insulator 12 surrounding the core conductor, and an outer conductor 13 surrounding the insulator 12 is provided. The core conductor 11 is made of a metallic material including copper and silver so as to have a tensile strength of 120 kg/mm² or more and an electric conductivity of 60 to 90% by IACS. The cable wire 1 is also employed in a coaxial cable 2 and a coaxial cable bundle.
