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.
