Abstract

A ceramic electronic component that includes a ceramic insulator and a terminal electrode on a surface of the ceramic insulator. The ceramic insulator contains a crystalline material and an amorphous material. The terminal electrode contains a metal and an oxide. The crystalline material and the oxide contain, in common, at least one type of a metal element. An adjacent region in the ceramic insulator which surrounds the terminal electrode and has a thickness of 5 μm is higher in concentration of the metal element than a remote region which is distant from the terminal electrode by 100 μm and has a thickness of 5 μm.
