    摘要: In order to provide dielectric ceramic composition having low IR defect rate and high relative dielectric constant even when the multilayer ceramic capacitor is made thinner, dielectric ceramic composition including a main component expressed by a composition formula {{Ba(1-x)Cax}O}A{Ti(1-y-z)ZryMgz}BO2 and subcomponents of Mn oxide, Y oxide, V oxide and Si oxide is provided. In the above formula, A, B, x, y and z are as follows: 0.995≦A/B≦1.020, 0.0001≦x≦0.07, preferably 0.001≦x
