Abstract
A ceramic electronic device includes an element body and an external electrode. The element body is formed by laminating a ceramic layer and an internal electrode layer. The external electrode is electrically connected to at least one end of the internal electrode layer. At least a part of a joint boundary between the electrode layer and the ceramic layer includes an interface protrusion on the external electrode side. The interface protrusion is made of an oxide.
