Abstract: A rolled type ceramic capacitor produced by the process comprising the steps of forming first and second inner electrodes alternately formed across insulating gaps on one surface of a single ceramic green sheet, rolling the ceramic green sheet with the inner electrodes formed thereon, whereby the first and second inner electrodes opposing to each other with the ceramic green sheet intervening therebetween, firing the rolled ceramic green sheet, and electrically connecting first and second outer electrode to the first and second inner electrodes, respectively. The ceramic capacitor can attain small size for large capacitance.

Abstract: A laminated ceramic capacitor, comprising a plurality of internal electrodes (1) composed of a base metal to give electrostatic capacity and configured in a laminated state with non-reducing ceramics (2) mutually held between each of two of the internal electrodes, and a pair of external electrodes (3) connected to the associated ones of the internal electrodes (1) for taking out the electrostatic capacity.
