    • A plasma processing apparatus is provided which does not require replacement of a band eliminator according to a frequency used, which is capable of performing chamber cleaning without replacing a resonance circuit, and which is capable of performing plasma cleaning of the inside of the chamber without using a bellows. The plasma processing apparatus includes a resonance circuit (band eliminator) for causing series resonance with a microwave circuit formed of at least a susceptor electrode and a processing chamber in order to trap plasma between a plasma excitation electrode and the susceptor electrode when the surface of a workpiece placed on the susceptor electrode is processed by plasma generated between the plasma excitation electrode and the susceptor electrode, which are provided inside the processing chamber; and for causing parallel resonance with the microwave circuit in order to diffuse plasma inside the processing chamber when performing plasma cleaning.
