Abstract:
1. An electrolytic processing method comprising: disposing a workpiece, to which electricity is fed from a feeding electrode, and a processing electrode such that they are not in contact with and close to each other at a distance of not more than 10 μm; supplying a liquid containing an ion-exchange material between the workpiece and at least one of the processing electrode and the feeding electrode so that the liquid flows therebetween, the ion-exchange material having a smaller size than the distance between the workpiece and the at least one of the processing electrode and the feeding electrode, and being present in a particulate or gel-like form in the liquid; applying a voltage between the processing electrode and the feeding electrode; and moving the workpiece and at least one of the processing electrode and the feeding electrode relative to each other.
