PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing an electrolytic aluminum foil, which prevents the aluminum foil from having uneven thickness due to drops of dew condensation products of alkyl sulfone in the apparatus.SOLUTION: In an apparatus for manufacturing an electrolytic aluminum foil, aluminum to be a foil is deposited on the surface of a cathode drum 1c while turning the cathode drum. The apparatus includes: a plating bath 1b for storing plating liquid in which the cathode drum and an anode plate 1d are soaked; a lid part 1a arranged on the plating bath so as to cover the upper part of the plating liquid; and a gas supply port 1g arranged in the lid part so that inert gas can be supplied. When depositing the aluminum foil, inert gas between the plating liquid and the lid part is kept at a temperature of 110°C or higher. |
