PURPOSE:To prevent minor short circuit caused by pinholes by forming a layer mainly comprising a positive electrode material, and electrolyte, and a binder and a layer mainly comprising a negative electrode material, the electrolyte, and the binder at some intervals on one side of a layer mainly comprising the electrolyte and the binder. CONSTITUTION:Positive and negative carbon current collectors 2 are formed at some intervals on a base plate 1, and positive and negative electrodes 3 are formed on the carbon current collectors 2. Solid electrolyte layers 4 are formed by extending over the positive electrode 3 and the negative electrode 3. Since the solid electrolyte layer 4 which is not in contact with the electrode 3 exists between the electrodes, short circuit is avoided and self-discharge is also decreased. A copper chevrel compound is used as the electrode materials of both electrodes, and a copper ion conductor such as RbCu4IxCly solid electrolyte is preferably used as the electrolyte. AgxV2O5 may be used in the positive and negative electrodes and a silver ion conductor such as Ag6I4WO4 may also be used as the electrolyte. |
