PURPOSE:To remove gaseous hydrogen and sludge by leaving a space through which a plating soln. passes between an anode rod and a jacket covering the rod and by arranging plural projected bars around the jacket so as to stir the plating soln. CONSTITUTION:An anode rod 1 having a circular cross-section rotates on an electrically conductive hollow rotating shaft 2. A space through which a plating soln. passes is left between a jacket 4 and the anode rod 1, and the jacket 4 and the anode rod 1 rotate as one united body. Plural projected stripes 11 for stirring the plating soln. are arranged around the jacket 4 in the axial direction at regular intervals. Diaphragms 12 which pass only the plating soln. are spread among the stripes 11. When the anode rod 1 and the jacket 4 are rotated as one united body in a plating tank, generated hydrogen is removed by the stripes 11. Sludge formed in the plating soln. does not flow into the plating tank because of the diaphragms 12. The sludge is discharged together with the plating soln., and it is separated and removed.
