Patent ID: 7476303

Claim:
An electrolytic processing apparatus comprising: a holder for holding a workpiece; an electrode section including (i) a processing electrode, (ii) a feeding electrode for feeding electricity to the workpiece, (iii) a contact member, positioned between the workpiece held by the holder and the processing electrode, which comes into contact with the workpiece during processing, and (iv) a discharge portion, formed between the processing electrode and the contact member, for discharging metal ions, which have been taken from the workpiece, from the contact member during the processing of the workpiece in the presence of a liquid; a power source for supplying a voltage between the processing electrode and the feeding electrode; and a regeneration dummy electrode for contacting the contact member, wherein the regeneration dummy electrode contacts the contact member while the power source supplies a voltage between the processing electrode and the feeding electrode in the same manner as in the processing of the workpiece, thereby regenerating the contact member.
