Patent ID: 8367966

Claim:
A ceramic plasma reactor comprising: a plurality of electrodes each of which is formed of a plate-shaped ceramic dielectric body and an electrically conductive film disposed inside the ceramic dielectric body; wherein the plurality of electrodes is stacked along a stacking direction with a predetermined gap between adjacent electrodes of the plurality of electrodes, wherein a first unit electrode is formed to include a first electrode and a second electrode that are two adjacent electrodes of the plurality of electrodes with the predetermined gap therebetween in such a manner that a face of the first electrode facing away from the predetermined gap forms a part of a gas circulating portion, the gas circulating portion circulating gas introduced there through from a gas introducing portion formed at a first end portion of the gas circulating portion, wherein the first electrode has a plural number of through holes formed in the plate-shaped ceramic dielectric body and a plural number of through holes formed in the electrically conductive film at positions corresponding to the through holes formed in the plate-shaped ceramic dielectric body; the through holes formed in the plate-shaped ceramic dielectric body having a smaller diameter than that of the through holes formed in the electrically conductive film, and wherein the predetermined gap between the first electrode and the second electrode functions as a discharge portion when plasma is generated due to application of a voltage between the first electrode and the second electrode while circulating the gas introduced from the gas introducing portion.
