<p>A dielectric ceramic composition comprising at least a main component containing a dielectric oxide of a composition expressed by ä(Sr1-xCax)Oüm.(Ti1-yZry)O2 and a first subcomponent containing at least one type of compound selected from oxides of V, Nb, W, Ta, and Mo and/or compounds forming these oxides after firing, wherein the symbols m, x, and y showing the molar ratio of the composition in the formula contained in the main component are in relations of 0.94<m<1.08, 0≤x≤1.00, and 0≤y≤0.20 and the ratio of the first subcomponent with respect to 100 moles of the main component, which is converted to the metal element in the oxide, is 0.01 mole≤first subcomponent<2 moles. According to this dielectric ceramic composition, it is possible to obtain a superior resistance to reduction at the time of firing, obtain a superior capacity-temperature characteristic after firing, and improve the accelerated life of the insulation resistance. <IMAGE></p> |
