Summary: | Plasma is generated on the first condition between a cathode electrode and an anode electrode. Then, plasma is generated on the second condition different from the first condition. The second condition is for spreading plasma between the cathode electrode and the anode electrode in the outer peripheral direction as compared with the first condition. Accordingly, in addition to a deposit on the electrode, a deposit on the member provided in the vicinity of the outer periphery of the electrode can be immediately removed. |
