In the exemplary embodiments, a multiple electrode for interference current therapy includes individual contact parts for emplacement on the patient at the location of application, and from which connection lines lead to the operational apparatus, or the like. In order to guarantee as simple as possible an application of the electrode system, an extended area-flexible formed part of electrically insulating plastic has flexible, electrically conductive plastic parts, as electrode contact parts, embedded in a smooth fashion. A good adaptation of the electrode system to different contours of the application location on the patient's body thus results.
