PROBLEM TO BE SOLVED : To provide a dielectric ceramic composition which improves a relative dielectric constant and has good reliability and a ceramic electronic component in which this dielectric ceramic composition is applied to the dielectric layer.
SOLUTION : The dielectric ceramic composition includes a compound which is expressed by a formula of ABO3 (wherein A is Ba alone, or Ba and at least one selected from Ca and Sr, and B is Ti alone, or Ti and Zr) and has a perovskite-type crystal structure, and an oxide of a rare-earth element including Sc and Y. The dielectric ceramic composition includes a dielectric particle having a core-shell structure which has a core and a shell in which at least R element is contained, and in the shell, the region showing a maximum content ratio of R element is a boundary region between the core and the shell.
