PURPOSE: An electrode for an electric discharge apparatus and a re-processing method thereof are provided to reduce processing time because the electrode is formed in a cylindrical shape. CONSTITUTION: A re-processing method of an electrode for an electric discharge apparatus is as follows. Each electric pole(10) having a worn electrode(11) is separated from a jig(15). The worn electrodes are cut at a milling machine. Each grinding unit(12) formed in the top of the electric pole is processed through the cut electrode. The bottom end of each electrode is processed by the grinding unit. The electric poles are fixed to joining holes(14) of the jig.
