Abstract: A multi-terminal capacitor is provided that can be used either as a feedthrough capacitor or as a LW reversal capacitor. A multi-terminal capacitor includes a capacitor body shaped like a rectangular parallelepiped. The capacitor body includes a capacitance forming portion configured to form capacitance between a first conductor film and a second conductor film facing each other with a dielectric film being interposed therebetween. On one of the surfaces of the capacitor body in the third direction, first and second external terminals electrically connected to the first conductor film, and a third external terminal electrically connected to the second conductor film are provided. On the other of the surfaces of the capacitor body in the third direction, fourth and fifth external terminals electrically connected to the first conductor film and a sixth external terminal electrically connected to the second conductor film are provided.

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.

Abstract: A ceramic electronic device includes a multilayer structure in which each of a plurality of dielectric layers including Ba and Ti and each of a plurality of internal electrode layers including Ni and Sn are alternately stacked. A discontinuity is formed in at least one of the plurality of internal electrode layers, the discontinuity being a break in a cross section including a stacking direction of the multilayer structure. An Sn high concentration portion, of which an Sn concentration is higher than an average Sn concentration of the one of the internal electrode layers, is formed on a part of a surface of the at least one of the internal electrode layers, the part of the surface being exposed to the discontinuity.
