Claim 0:
1. A ceramic electronic device comprising:
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,
wherein the three or more of internal electrode layers include Ni and Sn,
wherein 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,
wherein a Sn concentration of internal electrode layers from a center internal electrode layer to an outermost internal electrode layer in the stacking direction gradually gets larger or gets larger in steps from the center internal electrode layer to the outermost internal electrode layer in the stacking direction.
