An electrochemical element electrode for obtaining electrochemical elements having both low internal resistance and high capacitance, and a secondary battery and an electric double layer capacitor using the electrode are provided. An electrochemical element electrode which is made by forming an active material layer on a collector, and the active material layer is formed by press-molding composite particles with high strength at moderate pressure not to crush the composite particles under pressure, while the structures of the composite particles being maintained, to bond the composite particles together, wherein the composite particles comprise an electrode active material, an electric conductive material, a dispersible binder and a soluble resin, in which the electrode active material and the electric conductive material are bonded by the dispersible binder. By use of this electrode, an electric double layer capacitor or a secondary battery is obtained. |
