Abstract
An electrolytic processing apparatus can increase the efficiency of the dissociation reaction of water and efficiently perform electrolytic processing, and can eliminate the need for an operation of a change of ion exchanger. The electrolytic processing apparatus includes: a processing electrode and a feeding electrode; a liquid supply section for supplying a liquid containing an ion-exchange material between the workpiece and at least one of the processing electrode and the feeding electrode; a power source for applying a voltage between the processing electrode and the feeding electrode; and a drive section for moving the workpiece and at least one of the processing electrode and the feeding electrode relative to each other; wherein electrolytic processing of the workpiece is carried out while keeping the workpiece not in contact with but close to the processing electrode at a distance of not more than 10 μm.
