Zusammenfassung:PROBLEM TO BE SOLVED: To provide a current collector foil for a battery with a conductive coat on a surface of a metal foil and without wrinkles, to provide a method of manufacturing the foil, and to provide the battery using the current collector foil for the battery.SOLUTION: A current collector foil 32 for a battery comprises: a metal foil 33; and conductive coats 34A and 34B formed on a surface of the metal foil 33. The conductive coats 34A and 34B directly contact with metal composing the metal foil 33. The metal foil 33 comprises a recessed portion 33d recessed in a thickness direction of the metal foil 33 over the entire surface of the metal foil 33. Size of the recessed portion 33d related to the thickness direction of the metal foil 33 is 1 μm or more. The conductive coats 34A and 34B are formed on the surface of the metal foil 33 except the recessed portion 33d.
