PURPOSE:To provide a dielectric ceramic composition having a large dielectric constant, a large no-load Q, and a small temperature coefficient of a resonance frequency to be suitable as dielectric resonator material, etc. CONSTITUTION:Dielectric ceramic composition comprises barium, lead, neodymium, samarium, lanthanum, bismuth, titanium, and oxygen as expressed by a composition formula of (Ba1-xPbx)(Nd1-a-b-cSmaLabBic)2Ti4O12, where 0.01<=x<=0.3, 0.01<=a<=0.6, 0<=b<=0.3, 0.04<=c<=0.3, 0.05<=a+b+c<=0.90. |
