Beschreibung
Zusammenfassung:	The invention aims to provide a magnetron electrode for plasma treatment that is free of significant abnormal electrical discharge and able to perform electrical discharge with long-term stability. A second electrode is provided only at a position outside the inner side surface of the outer magnetic pole of a first electrode or at a position where the magnetic flux density is low.
