    摘要: A dielectric ceramic composition includes BaTiO3 as a main component; as subcomponents, with respect to 100 moles of BaTiO3, 0.9 to 2.0 moles of an oxide of RA in terms of RA2O3, where RA is at least one selected from Dy, Gd and Tb; 0.3 to 2.0 moles of an oxide of RB in terms of RB2O3, where RB is at least one selected from Ho and Y; 0.75 to 2.5 moles of an oxide of Yb in terms of Yb2O3; and 0.5 to 2.0 moles of an oxide of Mg in terms of Mg. when contents of oxide of RA, oxide of RB and oxide of Yb with respect to 100 moles of BaTiO3 are defined as “α”, “β” and “γ”, respectively, “α”, “β” and “γ” satisfy relations of 0.66≦(α/β)≦3.0 and 0.85≦(α+β)/γ≦2.4. According to the present invention, a dielectric ceramic composition having good properties can be provided.
