Abstract
A method for producing an aluminum film by electrodepositing aluminum on a base in an electrolytic cell to which a liquid electrolyte containing a molten salt is fed includes adjusting a concentration of an additive in such a manner that a measured value of an overvoltage is within a predetermined range on the basis of a predetermined relationship between the overvoltage and the concentration of the additive added to the molten salt upon electrodepositing aluminum in the liquid electrolyte.
