1. A dielectric ceramic composition comprising:
a base material main component of barium titanate and a subcomponent,
wherein the base material main component comprises a first base material main component represented by (Ba1-xCax)TiO3 (x≤0.035) and a second base material main component represented by (Ba1-yCay)TiO3 (0.035≤y≤0.135), and
a molar ratio of the first base material main component to the second base material main component is (1-z):z, in which 0.9≤z≤0.95.
