Abstract
The electrode comprises a metal substrate and a coated layer of an active material provided on one or both faces of the substrate. The metal substrate is a metal sheet having a plurality of punched holes. The punched holes have burrs along their peripheries so that the apparent thickness including the burrs is at least twice the original thickness of the metal sheet. The burrs improve the engagement between the metal substrate and the coated layer.
