Abstract
A plating apparatus capable of preventing difference in an electrode potential between the pair of cathodes and a disturbance in a current distribution in Haring cell test and so on is provided. A plating apparatus () has an anode () and a pair of cathodes (X) (Y) which are provided in a plating bathtub (); a plating power source () to supply an electric current between the anode () and the pair of cathodes (X) (Y); and a feedback circuit () to have an electrode potential of a first cathode (X) equal to an electrode potential of a second cathode (Y) while a summation of electric currents flowing through the pair of cathodes (X) (Y) is kept constant.
