Abstract

A multilayer ceramic capacitor includes outer electrodes at first and second end surfaces and coupled to inner electrode layers. Dielectric ceramic layers include crystal grains including a perovskite oxide. 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. When a thickness of the dielectric ceramic layers is denoted by d, at least a subset of the grains is provided in near-electrode regions located inside the dielectric ceramic layers and extending to a distance of about 0.1 d from interfaces with adjacent inner electrode layers.
