Abstract
A ceramic electronic device includes a multilayer chip in which each of a plurality of dielectric layers and each of a plurality of internal electrode layers including Ni as a main phase are alternately stacked. At least one of the plurality of dielectric layers includes a secondary phase including Si, at an interface between the at least one of the plurality of dielectric layers and one of the plurality of internal electrode layers next to the at least one of the plurality of dielectric layers. The one of the plurality of internal electrode layers includes a layer including an additive element including one or more of Au, Pt, Cu, Fe, Cr, Zn, and In, at a region contacting the secondary phase at the interface.
