Abstract:
A dielectric ceramic composition may include: a base powder represented by BaTiO3 and accessory components. In an XRD measurement of a dielectric material in which the base powder and the accessory components are sintered, when a (1, 1, 0) plane peak of a BaTiO3 crystal phase is converted into 1.00, a secondary phase peak of pyrochlore (RE2Ti2O7) (RE is a rare earth element) at about 30.5 degrees, as compared with the (1, 1, 0) plane peak, is 0.01 or less.
