Abstract
A dielectric ceramic that contains Al and Si, as well as a barium titanate-based compound having a perovskite type crystal structure as a primary component. The total molar amount of Al and Si is 2 to 4 parts by mole with respect to 100 parts by mole of Ti, and the content ratio of Al with respect to the total molar amount is 0.2 or less (excluding 0) on the molar ratio basis. The dielectric ceramic may also contain at least one specific rare earth element Re, such as Gd, Tb, or Dy.
