<p>A positive electrode (2a) and a negative electrode (2b) are formed on the two principal surfaces of a solid electrolyte (1). The solid electrolyte (1) is preferably formed into a 200μm or thinner thin film body, and contains a Li ion- or other ion-conductive compound. Further, ion conductive material layers (3a, 3b), e.g., metal Li layers, that contain the Li ion- or other ion-conductive compound are interposed at the interface between the solid electrolyte (1) and the positive electrode (2a), and at the interface between the solid electrolyte (1) and the negative electrode (2b). The ion conductive material layers (3a, 3b) are preferably 50-100nm thick. Use of the thin-film solid electrolyte makes it possible to achieve a large static capacitance despite the small size and a solid ion capacitor with excellent cycle characteristics.</p> |
