Abstract
An electrochemical device includes electrodes stacked one on the other with a separator intervening between the adjacent electrodes. The electrode includes a current collector and an electrode layer stacked on the current collector via an adhesive resin layer. The electrode layer contains an active material, an electrically conductive auxiliary and a binder resin. At least part of the electrically conductive auxiliary or the active material penetrates the adhesive resin layer to establish an electrical connection with the current collector.
