A ceramic electronic component includes a body, a first external electrode, and a second external electrode. The body includes a first end surface and a second end surface that face each other, surfaces each extending between the first end surface and the second end surface, an outer edge that is provided along the surfaces and includes recesses, the recesses extending from the first end surface and the second end surface along ridges of the surfaces, and a functional unit that is disposed inward relative to the outer edge. The first external electrode and the second external electrode respectively cover the first end surface and the second end surface and extend to come close to each other from the first end surface and the second end surface along the surfaces and the recesses.
