Abstract
There is provided a metal foil manufacturing method, in which a metal foil is manufactured by forming a thin metal layer by electrodepositing a metal on the surface of a cathode through an electrolytic reaction, and then separating the thin metal layer from the cathode surface. In doing this, an anodized film forming apparatus is mounted on an exposed surface of the cathode exposed after the separation of the metal layer, and is operated to subject the exposed surface of the cathode continuously or intermittently to electrolytic oxidation, thereby forming an anodized film on the exposed surface. The apparatus comprises electrolytic agent retaining means for retaining an electrolytic agent for anodization in contact with the exposed surface of the cathode, an electrode located in the electrolytic agent in the retaining means and supplied with an electrolytic current at a potential lower than the operating potential of the cathode, and electrolytic agent supply means for supplying the electrolytic agent to the electrolytic agent retaining means.
