ABSTRACT:
The non reducible dielectric ceramic composition comprising a main component of (Ba1-xCax)m(Ti1-yZry)O3, subcomponents of MgO, Re2O3, MO, MnO and V2O5where Re is one or more elements selected from the group of Y, Dy and Ho and M is one or two elements selected from the group of Ba and Ca, and a sintering aid of SiO2, wherein when the composition is represented by the formula 100(Ba1-xCax)m(Ti1-yZry)O3+bMgO+cRe2O3+dMO+eMnO+fV2O5+gSiO2, the ratio of the components satisfies the conditions of 0.005≦x≦0.15, 0.995≦m≦1.03, 0.0005≦y≦0.005, 0.1≦b≦3.0, 0.1≦c≦3.0, 0.05≦d≦2.0, 0.05≦e≦50.3, 0.0.≦f≦0.1, and 0.2≦g≦3.0 based on the molar ratio.
