Abstract
A high-dielectric constant ceramic composite is provided in which an appropriate amount of glass component is added to a composite of the BaTiO.sub.3 -PbMO.sub.3 group having a low temperature coefficient in the dielectric constant thereof. The added glass component serves to maintain the satisfactory properties of the ceramic composite even after various types of reliability tests.
