ABSTRACT:
A non-reduction type dielectric ceramic composition, which contains 100 parts by weight of (Ca.sub.1-x Sr.sub.x).sub.m (Zr.sub.1-y Ti.sub.y)O.sub.3 -zMnO.sub.2 -wSiO.sub.2 serving as a main component and 2 to 30 parts by weight of an additive which is a(LiO.sub.1.kappa. -RO)-(1-a)(BO.sub.3/2 -SiO.sub.2), where RO is at least one type of SrO, BaO and CaO, and a is not less than 0.01 nor more than 0.8 in terms of a molar ratio, and satisfies the following relationships in the composition formulas of the above described main component and additive: x, y and m satisfy the following relationships in terms of a molar ratio:
