A nonreducible dielectric ceramic composition consists essentially of a main component expressed by the formula: (Sr1-xCax)m(Ti1-yZry)O3 wherein x an dy are molar fractions of the respective elements, and m is molar ratio of (Sr1-xCax) to (Ti1-yZry), and wherein x, y and m take values within the following respective ranges: 0.30</=x</=0.50, 0.03</=y</=0.20, 0.95</=m</=1.08, and secondary components composed of at least manganese oxides and SiO2. The content of each secondary component per 100 parts by weight of the main component is 0.01 to 2.00 parts by weight for manganese oxides in terms of MnO2, and 0.10 to 4.00 parts by weight for SiO2. The composition may contain, as one of the secondary components, 0.01 to 1.00 parts by weight of MgO or ZnO per 100 parts by weight of the main component. The composition is useful as material for multilayer ceramic capacitors.
