Abstract

Composite conductor comprising a metallic conductor and a ceramic conductor or non-conductor, at least one of them being elongate, the two being connected with each other in an electrically conductive manner. The ceramic conductor or non-conductor and the metallic conductor are hard-soldered to each other by a contact surface extending obliquely to the longitudinal direction of the at least one elongate conductor, and has one of the conductors tapers at its end and the other conductor has a matching tapering recess. The tapering end of the conductor is fitted into the tapering recess.
