Provided are a metallic foil manufacturing method in which metallic film electrodeposited by electrolysis on the surface of an electrodeposition surface of a cathode is peeled off to form a metallic foil, and the electrodeposition surface used therein is obtained by subjecting a roughened surface, which results from roughening a smoothed surface made of titanium or titanium alloy using a blast treatment, etc., to an oxidation treatment selected from thermal oxidation, anodic oxidation (preferably anodic oxidation carried out while moving the anodic oxidation solution), or a combination treatment of thermal oxidation and anodic oxidation so that the electrodeposition surface has an oxidation layer with a thickness of 30 to 250 nm on the uppermost layer and has a surface roughness R7.JIS of 4 to 10 μm.
A method for manufacturing a metallic foil formed by peeling a metallic film electrodeposited by electrolysis on a surface of an electrodeposition surface of a cathode, the electrodeposition surface being formed by:
A cathode for manufacturing a metallic foil, the cathode being used for forming a metallic foil obtained by peeling off a metallic film electrodeposited by electrolysis on a surface of an electrodeposition surface of the cathode made of titanium or titanium alloy,
