The present invention provides an electrolytic processing apparatus which can suppress the growth of a gas, which is inevitably generated during electrochemical processing, into bubbles thereby effectively preventing the formation of pits in a surface of a workpiece. The electrolytic processing apparatus includes an electrode section (44) including processing electrodes (76) and feeding electrodes (78) both having a diameter of not more than 1 mm, a substrate holder (42) for holding a workpiece (W), a power source (46) for applying a voltage between the processing electrodes and the feeding electrodes, a fluid supply section (72) for supplying a fluid between the electrode section and the workpiece, and a drive section (56, 62) for moving the electrode section and the workpiece relative to each other in such a manner that the processing electrodes pass every point in a processing surface of the workpiece.
