Abstract

See full text

A ceramic electronic device includes a multilayer chip in which dielectric layers and internal electrode layers are alternately stacked. In an outermost one of the internal electrode layers, a metal oxide containing a main component element constituting the internal electrode layers is provided on an outer main surface of the outermost one, and a formation depth of the metal oxide is 0.5 μm or more and 5.0 μm or less. A segregation layer containing a sub metal element different from the main component metal is present at an interface between at least one of the internal electrode layers other than the outermost one and one of the dielectric layers adjacent to the at least one of the internal electrode layers.
