Abstract:
1. A plasma generating electrode comprising: at least a pair of unit electrodes disposed at a predetermined interval and capable of generating the plasma, each of the pair of unit electrodes including a plate-shaped ceramic body as a dielectric and a conductive film disposed inside the ceramic body and including a plurality of protrusions having a predetermined thickness and arranged in a predetermined pattern on one surface, a plurality of conductive film through-holes formed on the conductive film, the pair of unit electrodes (upper unit electrode and lower unit electrode) constituting one basic unit by being hierarchically layered at intervals corresponding to thickness of the protrusion in a state that a plurality of spaces which are open on each end in an arrangement direction of the protrusion are formed by a front surface of one unit electrode (lower unit electrode) of the pair of unit electrodes, surfaces of the protrusions disposed on the front surface, and a back surface of the other unit electrode (upper unit electrode), the basic units being hierarchically layered at intervals corresponding to the thickness of the protrusion and constituting an electrode unit in which the unit electrodes and the spaces are three-dimensionally arranged, and the plasma generating electrode being capable of generating the plasma in the three-dimensionally arranged spaces upon application of voltage between the unit electrodes constituting the electrode unit.
