A dielectroc ceramic composition and a monolithic ceramic capacitor using the composition are provided. The dielectric ceramic composition includes: barium titanate; at least one rare earth oxide selected from terbium oxide, dysprosium oxide, holmium oxide, erbium oxide and ytterbium oxide; manganese oxide and nickel oxide; and magnesium oxide in an amount of from 0.5 to 3.0 mols in terms of MgO, and silicon oxide in an amount of from 0.2 to 5.0 mols in terms of SiO2, relative to 100 mols of the essential component having the following compositional formula: (1-.alpha.-.beta.) {BaO}m~TiO2 + .alpha.Re2O3 + .beta.(Mn1-x Ni x)O where Re2O3 is at least one selected from Tb2O3, Dy2O3 Ho2O3, Er2O3 and Yb2O3; and .alpha., .beta., m and x are as follows: 0.0025 ~ .alpha. ~ 0.020 0.0025 ~ .beta. ~ 0.04 .beta./.alpha. 5 ~ 4 0.5 ~ x < 1.0 1.000 < m ~ 1.035.
