Original Abstract Submitted

A multilayer ceramic capacitor includes a body including dielectric ceramic layers and inner electrode layers. The dielectric ceramic layers include crystal grains including a perovskite oxide including at least one A-site element and at least one B-site element. When a cross-section of the dielectric ceramic layers is observed using a scanning transmission electron microscope, the dielectric ceramic layers include grains, on which a plane of a perovskite structure is observed, as crystal grains. In the cross-section, a percentage by number of the grains in the crystal grains is about 4% or more.
