ELECTROLYTIC PROCESSING APPARATUS AND ELECTROLYTIC PROCESSING METHOD

摘要

An electrolytic processing apparatus can maintain a difference in electric resistance between a recessed portion and a raised portion in the surface of a workpiece, thereby providing a processed surface with improved flatness. The electrolytic processing apparatus including: a processing electrode capable of bringing into contact with or closing to a workpiece; a feeding electrode for feeding electricity to the workpiece; a contact member disposed between the workpiece and at least one of the processing electrode and the feeding electrode, the degree of deformation of said contact member by a contact load applied from the workpiece being smal
