PURPOSE: An electrolytic polishing apparatus is provided to easily polish the overall inner and outer surfaces of a relatively large work piece by using a plurality of cathode plates fixed at regular intervals to one side of an object. CONSTITUTION: An electrolytic polishing apparatus comprises an electrolytic cell(110) receiving electrolyte and an object, a cathode holder(120) which is formed with a coupling part to be installed on one side of an object, cathode plates(130) which are submerged in the electrolyte and mounted to correspond to the object, C-type clamps(140) which fix the cathode plates at a constant interval from the object, and a rectifier(150) whose anode is connected to the object and cathode is connected to the object via the cathode plates, thereby supplying electricity.
