The composition of the present invention has a general formula: 100 (Ba 1−x Ca x ) m TiO 3 + aMnO + bCuO + cRO n (where the coefficients 100, a, b, and c represent molar ratios, and R represents Y, La, Ce, Pr) , Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, at least one metal element, n is a number determined by the valence of R, and maintains electrical neutrality A dielectric ceramic composition comprising a material represented by the following formula: and a sintering aid, wherein 0.990 ≦ m ≦ 1.050, 0.01 ≦ x ≦ 0.20, 0.5 ≦ a ≦ 3.5, 0.1 ≦ b ≦ 5.0, 10 ≦ c ≦ 20, the weight part d of the content of the sintering aid is against (Ba 1-x Ca x) m 100 parts by weight of the compound represented by TiO 3, satisfying 0.8 ≦ d ≦ 5.0 That. Furthermore, VO 3/2 is contained to increase the electric field at which dielectric breakdown occurs. |
