Abstract
A ceramic electronic device includes a multilayer structure in which each of a plurality of dielectric layers of which a main component is ceramic and each of three or more of internal electrode layers are alternately stacked. The three or more of internal electrode layers include Ni and Sn. An internal electrode layer having a larger Sn concentration is closer to an outermost edge in a stacking direction than an internal electrode layer having a smaller Sn concentration and being located on a center side of the stacking direction, in a relationship of at least two of the three or more of internal electrode layers.
