ABSTRACT:
A conductor has a core wire and a surface coated with the same kind of material as the core wire material. A copper wire (1) which forms the core wire has its surface cleaned by a preparatory processing mechanism (3) and then it is fed to a continuous sputtering unit (4). The continuous sputtering unit (4) coats the surface of the core wire (1) with copper by a coaxial magnetron sputtering method. Thereafter, this wire is drawn, by cold working, into a thin wire of predetermined size.
