Abstract
A ceramic capacitor comprises a column-like ceramic element having end faces provided with electrodes, respectively. A disk-like reinforcing element is secured to at least one of the electrodes in close contact therewith. The thickness T and diameter D of the ceramic element are selected so that T/D.ltoreq.0.5 and D.sub.t /D.gtoreq.0.6 where D.sub.t represents the thickness of the reinforcing metal member. The dielectric breakdown field strength appearing upon application of a chopped-wave impulse voltage can be increased at least to the dielectric breakdown field strength appearing upon application of a full-wave impulse voltage.
