Abstract
The invention relates to a dielectric ceramic composition that can be baked in a short time in the atmosphere, neutral atmosphere or reducing atmosphere at baking temperature of 800.degree. to 1000.degree. C. In the ceramic components expressed by PbTi.sub.X (Mg.sub.1/2 Nb.sub.2/3).sub.Y (Ni.sub.1/2 W.sub.1/2)ZO.sub.3 (where X+Y+Z=1), PbO is added by 1.0 to 25.0 mol % and NiO by 1.0 to 15.0 mol % as subsidiary components, to the temporarily baked powder of the main component dielectric ceramic composition composed in the pentagonal region having the vertices at compositions A, B, C, D, E expressed by numerical values in the following square brackets, in the system of trigonometric coordinates having the vertices at PbTiO.sub.3, Pb(Mg.sub.1/3 Nb.sub.2/3)O.sub.3 and Pb(Ni.sub.1/2 W.sub.1/2)O.sub.3,
