Ceramic electronic device with inflected external electrodes

A ceramic electronic device comprising:

• a multilayer chip in which dielectric layers of which a main component is ceramic are stacked, the multilayer chip having a rectangular parallelepiped shape and having two end faces facing with each other, an upper face and a lower face in a stacking direction of the dielectric layers, and two side faces that are other than the two end faces, the upper face and the lower face;
• a plurality of internal electrode layers that are provided inside of the multilayer chip and are extending to the two end faces;
• and
• a pair of external electrodes that are respectively provided on the two end faces and are connected to the plurality of internal electrode layers,
• wherein each of the pair of external electrodes has a smaller thickness in a region not connected directly to the plurality of internal electrode layers on corresponding end face as measured in a direction perpendicular to the corresponding end face, has an inwardly inflected point as viewed toward the plurality of internal electrode layers, and has a larger thickness in a region connected directly to the plurality of internal electrode layers on the corresponding end face as measured in a direction perpendicular to the corresponding end face, in above order in a direction connecting the two side faces,
• wherein the multilayer chip has a side margin region that covers ends of the plurality of internal electrode layers on each of the two sides,
• the larger thickness is provided on the region connected directly to the plurality of internal electrode layers on the corresponding end face wherein the large thickness extends to and within a part of the side margin region on the corresponding end face as viewed in a direction connecting the two end faces, and
• a portion corresponding to the smaller thickness and a portion corresponding to the larger thickness of the external electrodes are compositionally same and form an integral body.
