PROBLEM TO BE SOLVED: To prevent the adhesion of plating to a contactor. SOLUTION: The portions of the contactor 40 exclusive of its energizing member 41 are enclosed by insulating members 44, 45 and inert fluid is supplied to its contact point (46+42+43). Bias voltage is otherwise impressed to the front end of the contactor or its circumference. As a result, the infiltration of a plating liquid 23 is prohibited and, therefore, even if a plating layer 16 is formed by energizing the object 10 for plating from a power feed source 27 via the contactor 40, the contactor 40 including the contact point is not plated.
