<p>[Problem] To provide a dielectric ceramic composition which is mainly composed of BaTiO3, is co-sinterable with a metal that is mainly composed of Cu and has excellent electrical conductivity at a low temperature of 1030°C or less, and has high dielectric constant and excellent life characteristics. [Solution] A dielectric ceramic composition which is represented by BaTiO3 + aRe2O3 + bMnO + cV2O5 + dMoO3 + eCuO + fB2O3 + gLi2O + xSrO + yCaO (wherein Re represents one or more elements selected from among Eu, Gd, Dy, Ho, Er, Yb and Y; and a-h each represents the mole number of each component with respect to 100 mol of the main component that is composed of BaTiO3). When the molar ratio of (Ba + Sr + Ca)/Ti contained in the dielectric ceramic composition is represented by m, the 0.10 = a = 0.50, 0.20 = b = 0.80, 0 = c = 0.12, 0 = d = 0.07, 0.04 = c + d = 0.12, 0 = e = 1.00, 0.50 = f = 2.00, 0.6 = (100(m - 1) + 2g)/2f = 1.3, and 0.5 = 100(m - 1)/2g = 5.1 are satisfied.</p> |
