The non reducible dielectric ceramic composition comprising a main component of (Ba<SUB>1-x</SUB>Ca<SUB>x</SUB>)<SUB>m</SUB>(Ti<SUB>1-y</SUB>Zr<SUB>y</SUB>)O<SUB>3</SUB>, subcomponents of MgO, Re<SUB>2</SUB>O<SUB>3</SUB>, MO, MnO and V<SUB>2</SUB>O<SUB>5 </SUB>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<SUB>2</SUB>, wherein when the composition is represented by the formula 100(Ba<SUB>1-x</SUB>Ca<SUB>x</SUB>)<SUB>m</SUB>(Ti<SUB>1-y</SUB>Zr<SUB>y</SUB>)O<SUB>3</SUB>+bMgO+cRe<SUB>2</SUB>O<SUB>3</SUB>+dMO+eMnO+fV<SUB>2</SUB>O<SUB>5</SUB>+gSiO<SUB>2</SUB>, 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.
