Disclosed is a method to manufacture a cathode electrode plate. The cathode electrode plate manufacturing method according to an embodiment of the present invention includes; an ingot cutting step of cutting an ingot, which is to be manufactured as a cathode electrode plate, at a specific length; an ingot flattening step of flattening the upper and lower sides of the cut ingot; a lateral side processing step of processing the lateral side of the flattened ingot; an appearance processing step of forming the appearance of the cathode electrode plate in the ingot where the processing of the lateral side is performed; a drilling step of processing a gas passage hole, where plasma gas passes, in the cathode electrode plate where the appearance processing step is performed; and a polishing step of polishing the upper and lower sides of the cathode electrode plate where the drilling is completed. |
