PURPOSE:To obtain a dense plating layer having a smooth surface by passing a plating soln. through a penetrating hole in an anode plate, injecting the soln. onto a cathode, circulating the soln., and supplying the metal ion to be consumed in the vicinity of the cathode. CONSTITUTION:A member to be plated as the cathode plate 3 and the anode plate 2 having many penetrating holes 11 arranged in the form of a grille are provided in the electroplating tank in opposition to each other. The tank is filled with a plating soln. 9, and both electrodes 2 and 3 are dipped in the soln. The soln. 9 is jetted onto the cathode 3 through the holes 11. A plating soln. delivery mechanism is further provided, and the soln. 9 is circulated. |
