A problem to be solved by the invention is to provide an electrode for an electrochemical device which has a high capacity, suppresses the separation of an active material due to charge/discharge, and exhibits good cycle characteristics. To solve this problem, in the invention, an electrode 1 for an electrochemical device includes a current collector 2, an active material layer 4 formed over the current collector 2, and a thin layer 3 formed at least a part of the space between the current collector 2 and the active material layer 4. The active material layer 4 includes an active material which does not form a chemical bond with a component forming the current collector 2, and the like, and the thin layer 3 includes a component with a polarizability higher than that of the component forming the current collector 2. |
