An electrode substrate is formed by mechanically processing a nickel foil so as to be made three dimensional through the creation of concave and convex parts, and then, this substrate is filled with active material or the like so that an electrode is manufactured, wherein the above described concave and convex parts are rolling pressed so as to incline in one direction. Furthermore, an electrode for secondary battery is formed by using the above described method.
