Abstract

See full text

A ceramic electronic device includes a multilayer chip in which dielectric layers and internal electrode layers each including Ni as a main phase are alternately stacked. At least one of the dielectric layers includes Si. One of the internal electrode layers next to the at least one of the dielectric layers includes a layer including an additive element including one or more of Au, Pt, Cu, Fe, Cr, Zn, and In. A peak of a concentration of the additive element and/or a peak of a concentration of Si in the one of the internal electrode layers and the at least one of the dielectric layers exist(s) in a region within 15 nm in a thickness direction from an interface between the one of the internal electrode layers and the at least one of the dielectric layers.
