Abstract:
1. A dielectric ceramic composition comprising: a barium titanate as a main component; as subcomponents, with respect to 100 moles of said barium titanate, 0.9 to 2.0 moles of an oxide of RA in terms of RA 0.3 to 2.0 moles of an oxide of RB in terms of RB 0.75 to 2.5 moles of an oxide of Yb in terms of Yb 0.5 to 2.0 moles of an oxide of Mg in terms of Mg, wherein when contents of said oxide of RA, said oxide of RB and said oxide of Yb with respect to 100 moles of said barium titanate are defined as “α”, “β” and “γ”, respectively, said “α”, “β” and “γ” satisfy relations of 0.66≦(α/β)≦3.0 and 0.8≦(α+β)/γ≦2.4.
