Abstract
A ceramic electronic component includes a multilayer structure of a substantially rectangular parallelepiped shape constituted by alternately stacking dielectric layers mainly composed of ceramic and internal electrode layers alternately exposed to two edge faces opposite to each other of the multilayer structure, and cover layers mainly composed of ceramic and respectively disposed on top and bottom faces of the multilayer structure in a stack direction, wherein a Sn concentration with respect to a main component ceramic in the cover layer is higher than a Sn concentration with respect to a main component ceramic in a capacity section, the main component ceramic of each cover layer has a perovskite structure, and an atomic concentration ratio of Sn to B site elements in each cover layer is 0.005 or greater.
