Zusammenfassung:A dielectric ceramic composition includes main component grains having a perovskite structure represented by a formula AMO3. "A" includes Ba. "M" includes Ti. The dielectric ceramic composition includes a 4A subcomponent. The 4A subcomponent includes Fe and Mn. A molar ratio of Mn to a total of Fe and Mn in terms of a metal element is 0.18 to 0.65.
