ABSTRACT:
A solid electrolyte battery includes a battery element in which a cathode having a cathode composite mixture layer formed by applying a cathode composite mixture on a cathode current collector so as to provide a part to which the cathode composite mixture is not applied at an end part in the longitudinal direction of the cathode current collector and an anode having an anode composite mixture layer formed by applying an anode composite mixture on an anode current collector so as to provide a part to which the anode composite mixture is not applied at an end part in the longitudinal direction of the anode current collector are laminated so as to provide a solid electrolyte layer between the cathode and the anode. Porous members made of ceramics or non-woven fabrics are arranged between the longitudinal end parts of the cathode composite mixture layer and the longitudinal end parts of the anode composite mixture layer to extend to the parts of the cathode current collector to which the cathode composite mixture is not applied. Thus, a short-circuit in the end parts of the cathode composite mixture layer is prevented and yield upon manufacturing the solid electrolyte battery is improved.
