1. A planar electrode for medical purposes comprising two equally sized electrode surfaces, electrically separated along a linear insulation zone, which electrode surfaces adjoin directly along an inner edge portion, characterized in that:
said two equally sized electrode surfaces comprise, respectively, a bandshaped extension section, which encloses said other electrode surface along an outer edge portion and thereby is separated by said linear insulation zone from said respectively enclosed electrode surface, wherein said two electrode surfaces are formed approximately symmetrically around an axis perpendicular to the plane of said planar electrode, wherein respective terminal lugs are arranged at an end of one of said extension sections of said electrode surfaces and at a transition region between the other one of said electrode surfaces and said other extension section. |
