Abstract
An electrochemical device electrode pertaining to one mode of the present invention has a current collector, an aluminum oxide layer, a conductive layer, and an active material layer. The current collector is an aluminum foil. The aluminum oxide layer is formed on a principle surface of the current collector and contains aluminum hydroxide and aluminum oxide. The conductive layer is formed on the aluminum oxide layer and contains conductive material, while the active material layer is formed on the conductive layer.
