    摘要： A multilayer ceramic electronic component includes a ceramic body in which dielectric layers and internal electrodes are alternately stacked. The dielectric layers contain at least one dielectric grain having a ratio of a long axis to a short axis that is 3.5 or more. The internal electrodes contain a ceramic component containing a grain growth adjusting ingredient for dielectric grains. Each dielectric layer includes interfacial portions adjacent to the internal electrodes and a central portion disposed between the interfacial portions, and concentrations of the grain growth adjusting ingredient in the interfacial portions and the central portion are different from each other.
