PURPOSE:To provide a dielectric porcelain composition which is not transformed to a semiconductor even when baked in a reducing atmosphere and provides a high dielectric constant notwithstanding the crystal particle diameter being small. CONSTITUTION:This is a dielectric ceramic composition which contains a glass oxide of 0.05 to 5.0 parts by weight including a main component of BaO-SrO- Li2O-SiO2 in proportion to the following main component of 100 parts by weight: When each oxide of Mn and Ni is represented by MnO2 and NiO for a sub- component, at least one kind of the respective oxides of Mn and Ni is added to contain 0.02 to 2.0mol in proportion to 100mol of the main component which satisfies the following general formula: (Ba1-x-y-zCaxReyMgz)m (Ti1-o-pZroCop)O3 where (x), (y), (z), (o), (p) and (m) are to be 0.005<=x<=0.25, 0.0005<=y <=0.03, 0.005<=z<=0.05, 0< o<=0.20, 0.0005<=p<=0.03, 1.00<=m<=1.04. |
