Abstract:
1. A plasma generating electrode comprising: two types of plate-shaped unit electrodes of different polarities, the two types of unit electrodes of different polarities being hierarchically and alternately stacked at specific intervals, and a discharge space for generating plasma being formed between opposing unit electrodes, each of the unit electrodes of one polarity among the two types of unit electrodes of different polarities including a plate-shaped conductor exhibiting conductivity and a ceramic dielectric disposed to cover the conductor, the ceramic dielectric of the unit electrode of one polarity including a support protrusion for forming the discharge space for generating plasma between the opposing unit electrodes and at least a part of a space in which the unit electrode of the other polarity is disposed opposite to the unit electrode of one polarity and for supporting the unit electrode of one polarity, the support protrusion being integrally formed with the ceramic dielectric on at least one surface of the ceramic dielectric on at least one end of the ceramic dielectric in one direction, the support protrusions of adjacent unit electrodes of one polarity defining a gap, the gap defined at the at least one end of the ceramic dielectric in the one direction and extends from an interior side of the support protrusions at the end of the ceramic dielectric to an exterior side of the support protrusions, and both ends of the unit electrode of one polarity being integrally fixed to their respective support protrusions, with neither end of the unit electrode of the other polarity being integrally fixed to the support protrusions, and a stress on the support protrusions of the adjacent unit electrodes of one polarity supports the electrodes of the other polarity.
