A dielectric ceramic containing ABO3 in which A is Ba, possibly with at least one of Ca and Sr, and B is Ti, possibly with at least one of Zr and Hf as its main component, and Si as a accessory component. The dielectric ceramic includes main phase grains containing the ABO3 main component and secondary phase grains having a composition different from that of the main phase grains. The ratio of the Si content in the secondary phase grains to the total content of Si in the dielectric ceramic is 40% or more so that more Si is distributed in the secondary phase grains. It is preferable that the Si content in secondary phase grains be 30 mol% or more.
