    摘要： A solid electrolyte layer and electrode layers are formed within an electrically insulating frame part, and current collecting plates are held by the electrically insulating frame part. Since the current collecting plates are held by the frame part, the shifting or coming-apart of the current collecting plates can be restrained. In order to cause the current collecting plates to be held by the frame part, a powder of material of the electrode layer is filled in between the frame part and the current collecting plates.
