A ceramic electronic device includes: a ceramic main body that has internal electrode layers inside thereof and has a parallelepiped shape in which a part of one of the internal electrode layers is extracted to a first edge face of the parallelepiped shape and a part of another internal electrode layer is extracted to a second edge face of the parallelepiped shape facing the first edge face; external electrodes that are respectively formed on the first edge face and the second edge face and extend to at least one of side faces of the ceramic main body, wherein an interval between side edge portions of the external electrodes on the at least one of side faces is shorter than center portions of the external electrodes on the at least one of side faces.
