Claim 8:
9. A dielectric ceramic composition, comprising:
a barium titanate-based base material main component and a subcomponent,
wherein the subcomponent comprises a first subcomponent including at least one of oxides and carbonates of variable valence acceptor elements including at least one of Mn, V, Cr, Fe, Ni, Co, Cu, and Zn; a second subcomponent including at least one of oxides and carbonates of rare earth elements including at least one of Y, Dy, Ho, Er, Gd, Ce, Nd, Sm, Tb, Tm, La, Gd and Yb; a third subcomponent including at least one selected from a group consisting of oxides and carbonates of at least one of Ba and Ca; a fourth subcomponent including at least one selected from a group consisting of oxides and carbonates of Si; and a fifth subcomponent including at least one selected from a group consisting of oxides and carbonates of Mg,
wherein the first subcomponent includes Mn and V, and is contained so that a sum of variable valence acceptor elements of the first subcomponent per 100 mole of the base material main component is 0.15 mole or more and 1.02 mole or less,
wherein the second subcomponent includes Dy, and is contained so that a sum of the rare earth elements of the second subcomponent per 100 mole of the main component of the base material is 1.5 mole or more and 4.0 mole or less,
wherein the third subcomponent is contained so that a sum of Ba and Ca of the third subcomponent per 100 mole of the base material main component is 0.72 mole or more and 4.32 mole or less,
wherein the fourth subcomponent is contained so that a Si content of the fourth subcomponent is 0.5 mole or more and 3.0 mole or less per 100 mole of the base material main component,
wherein the fifth subcomponent is contained so that Mg of the fifth subcomponent is 0.27 mole or less per 100 mole of the base material main component,
wherein a ratio of a total content of the rare earth elements of the second subcomponent to the Mg content of the fifth subcomponent is 15 or more.
