Ceramic electronic component

A ceramic electronic component is provided. The ceramic electronic component includes: a body including a dielectric layer and an inner electrode; and an external electrode disposed on the main body and connected to the internal electrode. The dielectric layer includes a main phase having a perovskite structure represented by the formula ABO3, and the dielectric layer includes a region in which Dy is solid-solved. In the region in which Dy is solid-solved, the X-ray count of Dy solid-solved in the A-position of the perovskite structure as measured using a scanning transmission electron microscope-energy dispersive X-ray spectrometer (STEM-EDS) is AD, the X-ray count of Dy solid-solved in the B-position of the perovskite structure is BD, and the average value of AD/BD is 1.6 or more and 2.0 or less. 本公开提供一种陶瓷电子组件。所述陶瓷电子组件包括：主体，包括介电层和内电极；以及外电极，设置在所述主体上并连接到所述内电极。所述介电层包括主相，所述主相具有由式ABO3表示的钙钛矿结构，并且所述介电层包括固溶有Dy的区域。在固溶有Dy的所述区域中，通过使用扫描透射电子显微镜-能量色散X射线光谱仪(STEM-EDS)测量的固溶在所述钙钛矿结构的A位中的Dy的X射线计数为AD，固溶在所述钙钛矿结构的B位中的Dy的X射线计数为BD
