Claim 14:
15. 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 grain boundaries disposed between adjacent grains,
wherein the plurality of grains include at least one first grain,
wherein the first grain 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,
wherein an average Sn content of the grain boundary is defined as Cg, Sn average contents of the core, the first region, and the second region of the first grain are defined as C1, C2 and C3, respectively, and C2, Cg, C3, and C1 satisfy C2>Cg>C3>C1, and satisfy one or more of Cg≥1.1*C3, Cg≥2.0*C1 and C2≥1.3*Cg.
