PROBLEM TO BE SOLVED: To provide a method for producing a special shape electrodeposition capable of suppressing the greening and blackening of a special shape electrodeposition.SOLUTION: Into an electrolytic tank 1, together with a special cathode 4 masked with a surface insulator, a general cathode 3 not subjected to masking is dispersedly inserted, and electrolysis is performed. By the insertion of the general cathode 3 together with the special cathode 4, the electrodeposition areas of the whole bodies of the cathodes 3, 4 inserted into the electrolytic tank 1 increase to reduce current density. Further, the variation of the current density per cathode 3, 4 is reduced. As a result, the generation of the cathodes 3, 4 having high current density can be suppressed, and the greening and blackening of a special shape electrodeposition can be suppressed. |
