PURPOSE: A cathode plate for copper electro-refining having an anti-corrosive part in a welded portion is provided to increase copper extraction efficiency by preventing the corrosion of a hanger and an electrodeposited plate, thereby maximizing productivity. CONSTITUTION: A cathode plate for copper electro-refining comprises a hanger(11), a stainless electrodeposited plate(13), and an anti-corrosion unit(100). The hanger is formed in the shape of a rod having a square cross-section and has a longitudinal groove in the center of one side thereof. The upper end of an electrodeposited plate is inserted in the groove of the hanger, and a welded portion(20) is symmetrically welded to both sides of the cross-section of the electrodeposited plate. The anti-corrosion unit is arranged in the hanger and the welded portion of the stainless electrodeposited plate.
