PROBLEM TO BE SOLVED: To provide a conductor roll for a metallic foil which allows performance of an electroplating treatment to be increased by increasing an amount of current between the conductor roll and the metallic foil, in the electroplating treatment of a metallic foil with a thickness of 30μm or less. SOLUTION: The conductor rolls 10 and a backup rolls 11 are installed in the vicinity of each of a pair of inlets and outlets of insoluble electrodes 14. The conductor roll 10 is made of a metal, and is connected with a bus-bar 13 via a power supply 17. A roll deflection rate of the conductor roll 10 is set to be 0.04 to 0.05 mm/kg, and roll surface roughness of the conductor roll 10 is set to be 0.2 to 0.3μm. Thereby an amount of current between the conductor roll 10 and the metallic foil S is increased to 30-35 A/mm and consequently high quality plating is made available, and at the same time, the total number of electroplating cells 20 is significantly reduced.
