A ceramic electronic component includes a body including a dielectric layer and an internal electrode; and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer has a perovskite structure represented by a general formula ABOas a main phase, and includes a region in which Dy is dissolved. 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.

Ceramic electronic component

A ceramic electronic component includes a body including a dielectric layer and an internal electrode; and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer has a perovskite structure represented by a general formula ABOas a main phase, and includes a region in which Dy is solid solubilized. 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 measured by using Scanning Transmission Electron Microscopy-Energy Dispersive X-ray Spectroscopy (STEM-EDS) 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.
