CERAMIC ELECTRONIC DEVICE INCLUDING A MULTILAYER STRUCTURE WITH INTERNAL ELECTRODE LAYERS HAVING CERTAIN Sn CONCENTRATION

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 a plurality of internal electrode layers are alternately stacked in a stacking direction, the plurality of internal electrode layers including (i) a first internal electrode layer located at one end in the stacking direction, (ii) a second internal electrode layer located at a center in the stacking direction, and (iii) a third internal electrode layer located between the first internal electrode layer and the second internal electrode layer;
• wherein the first internal electrode layer, the second internal electrode layer, and the third internal electrode layer include Ni and Sn, and include Sn in a center of a first direction orthogonal to the stacking direction, and
• wherein a Sn concentration of the third internal electrode layer is higher than a Sn concentration of the second internal electrode layer.
