ABSTRACT:
A dielectric ceramic composition which has a high dielectric constant and a high Q value, as well as excellent temperature stability, and which is sinterable at a relatively low temperature. The dielectric ceramic composition of the present invention is formed of a mixture of a BaO--TiO.sub.2 --REO.sub.3/2 --BiO.sub.3 ceramic composition wherein RE represents a rare earth element, and a glass composition. The glass composition contains about 13-50 wt. % SiO.sub.2, about 3-30 wt. % B.sub.2 O.sub.3, about 40-80 wt. % alkaline earth metal oxide and about 0.1-10 wt. % Li.sub.2 O.
