Abstract
A dielectric ceramic composition includes a main component of a perovskite type compound represented by a general formula of ABO, in which A is an element in an A-site, B is an element in a B-site, and O is an oxygen element. A includes Ba. A further includes at least one of Ca and Sr. B includes Ti. A sintered-body lattice volume obtained by X-ray diffraction method is 64.33 Åor below.
