Provided is a dielectric ceramic in which, while achieving a dielectric constant epsilon of 500 or more, a breakdown voltage higher than 90 kV/mm can be obtained and which is suitable for constituting dielectric ceramic layers of a multilayer ceramic capacitor for medium-to-high voltage application. As the dielectric ceramic constituting dielectric ceramic layers of the multilayer ceramic capacitor, a dielectric ceramic including, as a main component, (Ba1-xCax)mTiO3 where 0.30<=x<=0.50, and 0.950<=m<=1.025 is used. Preferably, the dielectric ceramic further includes a rare-earth element in an amount of 1 to 14 parts by mole relative to 100 parts by mole of the main component, and further includes Mn, Mg, and Si, respectively, in amounts of 0.1 to 3.0 parts by mole, 0.5 to 5.0 parts by mole, and 1.0 to 5.0 parts by mole relative to 100 parts by mole of the main component.
