Dielectric ceramic composition and multilayer ceramic electronic component
A dielectric ceramic composition having improved insulation specific resistance and a highly accelerated lifetime. The dielectric ceramic composition includes a dielectric particle having a core-shell structure including a main component expressed by a general formula ABO3, where A is Ba and the like, and B is Ti and the like), and a rare earth element component R, in which a shell part of the core-shell structure has an average rare earth element concentration C of 0.3 atom % or more. The rare earth element has a specified concentration gradient or concentration variation.
