A dielectric ceramic composition for high frequencies of Patent Document 1 has a firing temperature of as high as 1350° C. to 1400° C. and is unsuitable for use as a material for multilayer capacitors because of its excessively high firing temperature. A multilayer capacitor of Patent Document 2 requires a complicated time-consuming manufacturing process and may cause a structural defect due to a difference between the coefficients of thermal shrinkage of an adhesive layer and a ceramic layer, thereby causing difficulty in miniaturization and multilayering of a multilayer ceramic capacitor. A dielectric ceramic composition of the present invention is represented by the general formula, Mg<SUB>x</SUB>SiO<SUB>2+x</SUB>+aSr<SUB>y</SUB>TiO<SUB>2+y</SUB>, wherein x, y and a satisfy the relations of 1.70<=x<=1.99, 0.98<=y<=1.02, and 0.05<=a<=0.40, respectively.
