Claim:
1. A dielectric ceramic composition comprising a main ingredient of a base material and an accessory ingredient, wherein the main ingredient of the base material includes a first main ingredient containing BaTiO the main ingredient of the base material is represented by (1−x)BaTiO the accessory ingredient includes a first accessory ingredient containing one or more selected from the group consisting of oxides and carbonates of variable-valence acceptor elements containing one or more of manganese (Mn), vanadium (V), chromium (Cr), iron (Fe), nickel (Ni), cobalt (Co), copper (Cu), and zinc (Zn), and a third accessory ingredient containing one or more selected from the group consisting of oxides of one or more of yttrium (Y), dysprosium (Dy), samarium (Sm), gadolinium (Gd), holmium (Ho), erbium (Er), and ytterbium (Yb), and a sum of contents of one or more variable-valence acceptor elements of manganese (Mn), vanadium (V), chromium (Cr), iron (Fe), nickel (Ni), cobalt (Co), copper (Cu), and zinc (Zn), contained in the first accessory ingredient, is 0.1 to 5.0 parts by mole based on 100 parts by mole of the main ingredient of the base material.
