1. 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 has a perovskite structure represented by a formula ABO3 as a main phase, and includes a region in which Dy is solid solubilized, and
in the region in which the Dy is solid solubilized, an X-ray count of Dy solid-solubilized in an A-site of the perovskite structure is AD, an X-ray count of Dy solid-solubilized in a B-site of the perovskite structure is BD, and an average value of AD/BD is 1.6 or more and 2.0 or less.
