Abstract
A ceramic electronic component includes an interior part and an exterior part. The interior part includes an interior part dielectric layer and an internal electrode layer. The exterior part includes an exterior part dielectric layer. The exterior part is positioned outside the interior part along a laminating direction thereof. The interior part dielectric layer and the exterior part dielectric layer respectively contain barium titanate as a main component. β−α≥0.20 and α/β≤0.88 are satisfied, where α mol part and β mol part are respectively an amount of a rare earth element contained in the interior and exterior part dielectric layers, provided that an amount of barium titanate contained in the interior and exterior part dielectric layers is respectively 100 mol parts in terms of BaTiO.
