  • Patent number: 10262795
    Abstract: A multilayer ceramic electronic component includes a ceramic body in which dielectric layers and internal electrodes are alternately disposed. Ceramic-metal compound layers are disposed on interfaces between the internal electrodes and the dielectric layers. Additionally, in some examples, spaces between adjacent internal electrodes are fully occupied by the dielectric layers and the dielectric layers contain a ceramic-metal compound containing metal particle. The ceramic-metal compound layer may have an embossing type configuration or a dendrite type configuration.
