Abstract
A dielectric ceramic composition contains a main component including a perovskite-type compound and also contains a subcomponent. An A-site of the perovskite-type compound includes at least Ca, and a B-site of the perovskite-type compound includes at least Zr. The subcomponent includes Mn as a first subcomponent element. The first subcomponent element is present at both of an A-site and a B-site of the perovskite-type compound.
