Abstract
A ceramic electronic device includes: a multilayer structure having a parallelepiped shape in which each of dielectric layers and each of internal electrode layers are alternately stacked and are alternately exposed to two end faces; and a cover layer provided on at least one of an upper face and a lower face of the multilayer structure, a main component of the cover sheet being same as the main component of the plurality of dielectric layers, wherein tensile stress remains along a first direction on a surface of the cover layer, wherein the first direction is a direction in which the two end faces face with each other, wherein the tensile stress on a center side in a second direction is larger than the tensile stress on the two side faces side, wherein the second direction is a direction in which the two side faces face with each other.
