U.S. 2004247865 Pavan, F. Electrolytic process for depositing copper on a steel wire in which the wire travels through an acidic electrolytic bath of an aqueous solution of Cu (II) ions in the form of a salt of an acid. A direct electric current passes through the solution between at least one anode and the wire acting as the cathode. The bath also has from 1.9 to 6 mM/1 of a thiourea and from 1.9 to 6 raM/1 of an amino acid. Electrolytic Processing A p p a r a t u s and M e t h o d

The electrolytic processing a p p a r a t u s includes a pair of electrodes disposed at a given distance, an ion exchange m e m b r a n e disposed b e t w e e n the pair of electrodes, and a liquid supply section for supplying a liquid b e t w e e n the pair of electrodes. The electrolytic processing method includes providing an electrode section having a pair of electrodes disposed at a given distance with an ion exchanger being interposed; and bringing the electrode into contact with or close to a workpiece while supplying a fluid to the ion exchanger, thereby pro-
