A plurality of first and second capacitor parts and second capacitor parts are formed on opposed main surfaces of a foil shaped conductive substrate to sandwich the conductive substrate. The first and second capacitor parts are respectively coated with insulative protection layers. Terminal electrodes are respectively formed on main surfaces of the protection layers. The terminal electrodes and conductive parts of the first and second capacitor parts are respectively electrically connected via first via conductors and the terminal electrodes and the conductive substrate 1 are electrically connected to second via conductors.
