An object of the present invention is to provide a dielectric ceramic composition in which a volume changing ratio of the electrostatic capacity is within ±0.3% over a wide temperature range of -55 to +125° C., it satisfies the NPO characteristics regulated by EIA standard, the dielectric constant is high as 75 or more and the Q value of 2000 or higher and it is capable of subjecting to sintering at a low temperature of 1100 to 1150° C. The dielectric ceramic composition of the present invention is a (Ba Ca Sr Nd Gd)TiO3 series composition and to the composition was added and contained 1.0 to 5.0% by weight of ZnSiTiO5, 1.0 to 5.0% by weight of ZnSi2TiO7 or 1.0 to 5.0% by weight of CaSiTiO5 based on the weight of the composition.
