PURPOSE:To obtain the dielectric ceramic composition having a high dielectric constant, in which bismuth is not included in the composition thereof and the fluctuation of temperature change ratio of the electrostatic capacity is small over a wide temperature range and the loss of the dielectric is small. CONSTITUTION:As the main component, BaTiO3 at 94.0-99.0mole%, Nb2O5 at 0.5-3.0mole% and ZnO at 0.5-3.0mole% are included, and as the additional material, one kind or more of CaZrO3, SrZrO3, BaZrO3 at 0.2-7.0weight% is included. Furthermore, one kind or more of La2O3, Nd2O3, Pr6O11 at 0.5weight% or less is included at need. |
