Abstract
A ceramic electronic component includes a body, including a dielectric layer and an internal electrode. The dielectric layer includes a plurality of dielectric grains, and at least one of the plurality of dielectric grains has a core-dual shell structure having a core and a dual shell. The dual shell includes a first shell, surrounding at least a portion of the core, and a second shell, surrounding at least a portion of the first shell. The dual shell includes different types of rare earth elements R1 and R2, and R2/R1is 0.01 or less and R2/R1is 0.5 to 3.0, where R1and R1denote concentrations of R1 included in the first shell and the second shell, respectively, and R2and R2denote concentrations of R2 included in the first shell and the second shell, respectively.
