Abstract
The object of the present invention is to provide the dielectric ceramic composition having good characteristics even under the high electric field intensity, and particularly good IR characteristic and the high temperature accelerated lifetime. The dielectric ceramic composition according to the present invention comprises a main component comprising a perovskite type compound shown by a compositional formula (Ba1-x-ySrxCay)m(Ti1-zZrz)O3 (note that, said “m”, “x”, “y” and “z” all show a mol ratio, and each satisfies 0.94≤m≤1.1, 0≤x≤0.2, 0≤y≤0.2, 0.06≤z<0.2),
