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 general formula ABO3 as a main phase, and includes a region in which Dy is dissolved, and
in the region in which Dy is dissolved, an atomic ratio of a content of Dy dissolved in an A-site of the perovskite structure to a content of Dy dissolved in a B-site is 1.6 or more and 2.0 or less.
