Abstract

A multi-element electrode comprises at least two flat partial electrodes which are arranged in juxtaposition to a pre-established direction. To simplify the fabrication of such an electrode and in particular to allow the use of cable conductors of equal length for attachment thereto, provision is made for the two partial electrodes to exhibit facing edges which are at an angle to the pre-established direction. Such a construction is advantageous in the case of a three-part electrode. The electrode is preferably the neutral electrode of an HF-surgical apparatus.
