PURPOSE:To provide a dielectric ceramic composition having high dielectric constant and small in changing ratio of volume by temperature, further capable of corresponding to the formation of thin layer having <=10mum thickness, free from secondary phase and having uniform structure. CONSTITUTION:The dielectric ceramic composition contains a main component consisting of 92.0-99.4mol% BaTiO3 having <=0.04wt.% content of an alkali metal oxide contained as impurity, 0.3-4.0mol% at least one rare earth oxide (Re2O3) selected from Tb2O3, Dy2O3, Ho2O3 and Er2O3 and 0.3-4.0mol% NiO and a subsidiary component consisting of 0.2-5.0mol% and 0.05-1.0mol% MnO based on 100mol% main component. |
