PURPOSE:To provide dielectric ceramic composition having a large dielectric constant, a large no-load Q, and small temperature change of a resonance frequency. CONSTITUTION:Mg of 1.2wt.% or less as converted into oxide is included in oxide expressed by a composition formula of (Ba1-xPbx)(Nd1-y-zSmyBiz)2+ATi4+BO12+3A/2+2B, where 0.01<=x<=0.4, 0<=y<=0.8, 0.1<=z<=0.4, -0.5<=A<=+0.5, -0.5<=B<=+0.5, 0.1<=y+z<=1. |
