Abstract
This invention provides a dielectric ceramic composition which has a high dielectric constant and a high Q value, and also has lower temperature coefficient of resonance frequency. The dielectric ceramic composition is attained by sintering composition which comprises a first component from 40 to 98 wt % and a second component from 2 to 60 wt %. The first component is represented by the following formula, EQU Ca{(Mg.sub.1/3 Nb.sub.2/3).sub.1-x Ti.sub.x }O.sub.3 where 0.ltoreq.x.ltoreq.0.50. The second component includes at least one element selected from the group consisting of SiO.sub.2 and B.sub.2 O.sub.3.
