DIELECTRIC CERAMIC COMPOSITION AND MULTILAYER CERAMIC ELECTRONIC DEVICE
A dielectric ceramic composition includes a first crystal grain that has a perovskite structure expressed by a general formula of BaTiO3, and has a core portion and a shell portion surrounding the core portion and including dysprosium, and a second crystal grain in which an elemental ratio of barium to titanium is 0.70 or less and a main component is barium titanate composite oxide. An elemental ratio of barium to titanium of the dielectric ceramic composition is 0.90 or more and 0.98 or less.
