Claim 13:
14. 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 and V; a second subcomponent including at least one of oxides and carbonates of Dy; a third subcomponent including at least one selected from a group consisting of oxides and carbonates of at least one of Ba and Ca; and a fourth subcomponent including at least one selected from a group consisting of oxides and carbonates of Si,
wherein a sum of Mn and V is 0.15 mole or more and 1.02 mole or less per 100 mole of the base material main component,
wherein Dy is 1.5 mole or more and 4.0 mole or less per 100 mole of the main component of the base material,
wherein a sum of Ba and Ca is 0.72 mole or more and 4.32 mole or less per 100 mole of the base material main component,
wherein Si is 0.5 mole or more and 3.0 mole or less per 100 mole of the base material main component,
wherein a ratio of a total content of Ba and Ca to Si content is 1.20 or more and 2.00 or less.
