Claim 20:
21. A ceramic electronic component, comprising:
a body including a dielectric layer and an internal electrode; and
an external electrode disposed on the body and connected to the internal electrode,
wherein the dielectric layer includes a plurality of grains and a grain boundary disposed between adjacent grains,
wherein the plurality of grains include first grains, second grains, and third grains, the first grains, the second grains, and the third grains being different from each other,
wherein each of the first grains has a core-shell structure including a core and a shell surrounding the core, and the shell of the first grain includes a first region surrounding the core and a second region surrounding the first region, and Sn average contents of the core, the first region, and the second region of the first grain are different from each other,
each of the second grains has a core-shell structure including a core and a shell surrounding the core, and Sn average contents of the core and the shell of the second grain are different from each other,
each the third grains includes Sn more uniformly distributed than the first grains and the second grains, and
the number of the first grains is 5% or more and 50% or less of the total number of the plurality of grains.
