The invention provides a ceramic operating electrode and a making method thereof. The operating electrode comprises a ceramic scalpel, a round electrode bar and an injection-molded part, wherein the round electrode bar and the ceramic scalpel are connected by virtue of the injection-molded part; and one end of the round electrode bar is arranged in the ceramic scalpel. In comparison with a conventional operating electrode which can cause damage to sidewall due to a too large exposure area, the ceramic operating electrode provided by the invention can avoid thermal damage to the sidewall in deep operations; marginal discharge of the ceramic electrode is achieved, and discharge of the sidewall is prevented; with the operation of the operating electrode provided by the invention, soft tissuecutting and blood coagulation can be conducted in operations; and the ceramic operating electrode, which concentrates discharge in an electrode margin, can avoid sidewall discharge of the electrode.
