Claim 0:
1. A ceramic electronic component comprising:
a body including first and second internal electrodes overlapping each other with a dielectric layer disposed therebetween,
wherein dielectric grains of the dielectric layer have core-shell structures having a core and a shell surrounding at least a portion of the core and including a rare earth element in a concentration higher than the core,
wherein at least one of the dielectric grains has a core-dual shell structure having a core and a dual shell, the dual shell comprises a first shell surrounding at least a portion of the core and a second shell surrounding at least a portion of the first shell, and
wherein a thickness of the first shell along a straight line connecting α and β is 5 to 30% of a distance between α and β, where α denotes a center of the core-dual shell structure in a cross-section of the core-dual shell structure and β denotes a point on a surface of the second shell.
