Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nickel foil for a secondary battery collector which is not a porous nickel foil and does not undergo a specific surface treatment and has an improved active substance carrying property and has a large contacting area with the active substance and the nickel foil and has an excellent electric conductivity. SOLUTION: The nicke foil for a secondary battery collector has a concavo-convex shape and when one side surface of the nickel foil is depressed, the opposite side surface of the concavo-convex shape is in projected wave shapes or pyramid shapes which are dispersed and formed regularly over a plane surface of the nickel foil.
