Abstract: A battery electrode substrate is fabricated by the steps of applying a pressing force to a thin metal sheet by embossing to form an undulated portion over the entire surface, during the process of forming the undulated portion, forming holes in the apices of the undulated portion by a pressing force; producing burrs protruding outwardly from the edges of the holes; stacking the metal sheets formed with the undulated portions to combine the burr on the apex side of the raised portion of the lower layer of the adjoining metal sheets with the burr on the apex side of the recessed portion of the upper layer. This structure allows an active substance to be filled into a space formed between the upper and lower adjoining metal sheets through openings of the apices of the recessed and raised portions

Abstract: Concave portions and convex portions are formed on a peripheral surface of a thin metal sheet by applying a pressing force thereto while the metal sheet is being embossed; pores are each formed on an apex of each of the concave portions and convex portions and burrs each projecting outward from a peripheral edge of each of the pores are generated by the pressing force; the metal sheets having the concave portions and convex portions formed thereon are layered on each other; the burr at the apex of each convex portion of a lower-layer metal sheet is interlocked with the burr at the apex of each concave portion of an upper-layer metal sheet adjacent to the lower-layer metal sheet to integrate the metal sheets with each other; and an active substance is charged into spaces between the upper-layer metal sheet and the lower-layer metal sheet through an aperture at the apex of each of the concave portions and convex portions.
