摘要：
A dielectric ceramic composition comprises 100 parts by weight of a primary constituent, about 0.1 to 25 parts by weight of a first secondary constituent comprising a SiO2-based glass not containing lead oxide, and about 20 parts by weight or less of a second secondary constituent comprising manganese oxide (MnO). The primary constituent is represented by the formula x(Ba&agr;Ca&bgr;Sr&ggr;)O-y[(TiO2)1−m(ZrO2)m]-zRe2O3 wherein x+y+z=100 on a molar basis, &agr;+&bgr;+&ggr;=1, 0≦&bgr;+&ggr;≦0.8, 0
