PURPOSE:To provide a ceramic capacitor, which is small in size, large in capacity, and high in CR product at a high temperature, at a low cost. CONSTITUTION:A dielectric ceramic composition is composed of 100.0 parts by weight of basic component and 0.2 to 5.0 parts by weight of additive component, wherein the basic component is expressed by a composition formula, (1-alpha-beta)(Bak-(x+y)MxLy)Ok(Ti1-zRz)O2-z/2+alphaBaZrO3+betaMgNb2O6 (where M is Mg and/or Zn, L is Ca and/or Sr, R is one or more elements selected from Sc, Y, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu), and the additive component is composed of Li2O, SiO2, and MO (where MO is one or more kinds of oxides selected from BaO, SrO, CaO, MgO, and ZnO). |
