PURPOSE:To accomplish an electrochemical element having stable bond with solid electrolyte by forming electrode from a plurality of materials, which are laminated one over another while the mix proportion is varied in steps. CONSTITUTION:A plurality of materials are used mixedly and laminated one over another to form an electrode 2, wherein the mix proportion is varied in steps. That is, the laminative constitution of electrode shall be such that a materials, which is non-reactive with solid electrolyte 1 and having equal thermo-expansion characteristics to the solid electrolyte 1, is used to the innermost part 4 in contact with the solid electrolyte 1, and that the content of a material or materials not having the matching property with solid electrolyte 1 about thermo-expansion etc., but having excellent electroconductivity increases outward in steps. This enables stabilization of the bond of the interface between electrode 2 and electrolyte 1. |
