PURPOSE:To provide a coaxial wire having favorable performance by forming fluorinated carbon resin coating on the surface of metal conductor, forming metal coating on it by sputtering, and electroplating metal on the surface of it. CONSTITUTION:Fluorinated carbon resin coating 2 of polyethylene propylene fluoride or the like having favorable high-frequency characteristics is formed on the surface of a metal conductor 1 of Cu or the like, and a thin film 3 of Cu is formed on it in a sputtering method using a ring of a sputter target of Cu. Next, a metal plating layer 4 of Cu, Al, Ni, etc., is formed on it in an electroplating method, thereby a coaxial wire having favorable electric characteristics can be provided. |
