A dielectric ceramic composition and a monolithic ceramic capacitor using same are provided. The dielectric ceramic composition includes: barium titanate; scandium oxide, yttrium oxide, manganese oxide and nickel oxide, magnesium oxide, as a side component, 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.M2O3 + .beta.(Mn1-xNix)O where M2O3 is at least one selected from Sc2O3 and Y2O3; and .alpha., .beta., m and x are as follows: 0.0025 ~ .alpha. ~ 0.020 0.0025 ~ .beta. ~ 0.04 .beta./.alpha. ~ 4 0 ~ x < 1.0 1.000 < m ~ 1.035.
