An electrosurgical body electrode to serve as the return electrode in electrosurgical procedures, adapted to be attached to a patient's body, comprises a base cover sheet, a thin, flexible electrically-conductive metal plate adjacent the inner side of the coversheet, a thin, substantially uniform dielectric layer, e.g. polyester film, partially or completely covering the metal plate on the body attaching side, along with adhesive sections for releasably attaching the electrode to the patient's body skin and an electrical connector for connecting the metal plate into an electrical circuit. The electrode causes capacitive coupling of the body into the electrical circuit, for return of the high frequency electric current used in electrosurgical procedures. The cover sheet is stretchable, to press the metal plate into contact with the body of the patient, and includes a stretch indicator to show the operative that the plate is in proper contact under the stretched cover sheet.
