Disclosed herein is a dielectric ceramic composition based on a lead-based perovskite-type complex compound containing nickel, characterized in that the amount of nickel is smaller than the stoichiometric amount. The dielectric ceramic composition can contain alpha mol % (0< alpha </=100) of lead-based perovskite-type complex compound represented by the formula belowPb[Ni(1-x)/3A2/3]a[Ni(1-y)/2D1/2](1-a)O3where A denotes at least one element selected from elements having a valance of +5, D denotes at least one element selected from elements having a valance of +6, 0<x<1, 0<y<1, and 0</=a</=1, with the amount of nickel being gamma mol % (0< gamma </=20) which is smaller than the stoichiometric amount (where gamma = alpha x(axxx+E,fra 1/3+EE +(1-a)xyx+E,fra 1/2+EE )). The dielectric ceramics composition which has a high dielectric constant and yet has nearly constant capacity-temperature characteristics.
