Abstract
A multilayer ceramic electronic device includes a plurality of internal electrode layers, a plurality of dielectric layers, each of which has a perovskite structure that is expressed by a general formula of ABO, a pair of cover layers respectively provided on an upper end and a lower end in a stacking direction in a capacity section, and has a main component that is a same as a main component of the plurality of dielectric layers. The capacity section has a first section positioned in a center portion in the stacking direction and a pair of second sections outside of the first section in the stacking direction. An A/B ratio of the first section is larger than the A/B ratio of the second section. The A/B ratio of the pair of cover layers is larger than the A/B ratio of the first section.
