Abstract

A connecting wire having an electrically conductive core, preferably provided by a wire or ribbon, with a coating provided on the surface of the core. The coating is composed of a nitrogen-containing tantalum alloy or tungsten alloy, and also optionally contains silicon as an additional alloy component. A manufacturing method for producing such a connecting wire involves passing a wire or ribbon core past a coating source to apply the coating.
