摘要： In a dielectric ceramic composition comprising TiO.sub.2 and ZnO as a main component, B.sub.2 O.sub.3 and/or a B.sub.2 O.sub.3 -containing vitreous component is contained as an auxiliary component. This establishes a low-temperature firing capability which permits Ag, Cu, Ag base alloy or Cu base alloy to be used as an internal conductor. A choice of a compositional ratio of the main component enables a choice of a temperature coefficient while a choice of the content of the auxiliary component enables a choice of a sintering temperature. It is further possible to control the crystalline structure, dielectric constant, Q value, temperature coefficient, insulation resistance (IR) and grain size of the composition by adding a Cu oxide, Ni oxide, Mn oxide, and Si oxide and adjusting their contents.
