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 are alternately stacked. There are a concentration peak of a first metal and a concentration peak of a second metal at different positions in a stacking direction of the plurality of internal electrode layers and the plurality of dielectric layers between a dielectric layer and an internal electrode layer next to the dielectric layer, the first metal and the second metal being different from a main component metal of the plurality of internal electrode layers. The second metal is easier to ionize than the first metal. The concentration peak of the second metal is closer to the dielectric layer than the concentration peak of the first metal.
