Abstract
A dielectric ceramic exhibiting a high dielectric constant is provided. The relative dielectric constant of the dielectric ceramic is stable with respect to temperature dependence and exhibits insulation resistance having a reduced voltage dependence. The dielectric ceramic of the invention can be used to form a multilayer ceramic capacitor that has a long life.
