A monolithic ceramic capacitor having a plurality of dielectric ceramic layers, internal electrodes, and external electrodes electrically connected to the internal electrode, wherein the dielectric ceramic layers comprise (a) barium titanate having an alkali metal oxide impurity content of not more than about 0.02% by weight, (b) scandium oxide and/or yttrium oxide, (c) gadolinium oxide, terbium oxide and/or dysprosium oxide, (d) manganese oxide, (e) cobalt oxide, and (f) nickel oxide, and is a material containing (1) 100 mols represented by the compositional formula: (1- alpha - beta ){BaO}m.TiO2+ alpha {(1-x)M2O3+xRe2O3}+ beta (Mn1-y-zNiyCoz)O wherein M2O3 represents the above-mentioned (b); Re2O3 represents the above-mentioned (c); 0.0025</= beta </=0.05; beta / alpha </=4; 0<x</=0.50; 0</=1.0; 0</=z1.0; 0</=y+z<1.0; and 1.000<m</=1.035, (2) about 0.5 to 5.0 mol, in terms of MgO, of magnesium oxide and (3) about 0.2 to 3.0 parts by weight, per 100 pph of components (1) and (2), of SiO2-TiO2-MO-based oxide glass (wherein MO represents at least one member selected from the group consisting of BaO, CaO, SrO, MgO, ZnO, and MnO). The internal electrodes can be nickel or a nickel alloy.
