Claim:
A non reducible dielectric ceramic composition, comprising: a main component of (Ba 1-x Ca x ) m (Ti 1-y Zr y )O 3 ; subcomponents of MgO, Re 2 O 3 , MO, MnO and V 2 O 5 where 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 SiO 2 , wherein when the composition is represented by the formula 100(Ba 1-x Ca x ) m (Ti 1-y Zr y )O 3 +bMgO+cRe 2 O 3 +dMO+eMnO+fV 2 O 5 +gSiO 2 , 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≦0.3, 0.0≦f≦0.1, and 0.2≦g≦3.0 based on the molar ratio.
