Abstract: A dielectric ceramic composition includes a main component of a perovskite type compound represented by a general formula of ABO3, 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. B includes Ti and Zr. A sintered-body lattice volume obtained by X-ray diffraction method is 64.50 Å3 or above.
