An electrode arrangement is described that is configured to be coupled to a high voltage source for a dielectric barrier discharge plasma treatment of an irregularly three-dimensionally shaped surface of an electrically conducting body. The three-dimensionally shaped surface is used as a counter electrode. A first planar electrode is coupled to the high voltage source via a first lead, fitted to the object to be treated and brought in contact with a dielectric. A second electrode is contacted with the surface to be treated as reference electrode. The second electrode is provided in an edge portion that is circumferential to the first planar electrode and configured to be coupled to a reference voltage source via a second lead. An isolating cover layer covers the electrode and a third electrode covers the isolating cover layer as a ground electrode.
