  • Patent number: 9236187
    Abstract: A multilayer ceramic capacitor includes a ceramic main body including an inner layer portion including third ceramic layers and a plurality of inner electrodes arranged at interfaces between the third ceramic layers, and first and second outer layer portions respectively including first and second ceramic layers, the first and second ceramic layers being arranged vertically so as to sandwich the inner layer portion. The third ceramic layers and the first and second outer layer portions contain a perovskite-type compound represented by ABO3 where A contains one or more of Ba, Sr, and Ca, B contains one or more of Ti, Zr, and Hf, and O represents oxygen) as a main component. Where a rare-earth element concentration (CR) in the third ceramic layers is compared to a rare-earth element concentration (Cr) in outermost layer portions including at least outermost surfaces of the first and second outer layer portions, CR>Cr (inclusive of Cr=0).

  • Publication number: 20160005543
    Abstract: A multilayer ceramic capacitor includes a laminated body including an inner layer portion including ceramic dielectric layers and internal electrodes, and outer layer portions including ceramic dielectric layers. External electrodes connected to the internal electrodes are provided on both ends of the laminated body. The main constituent of the inner layer portion is a perovskite-type compound represented by ABO3. The outer layer portions include first outer layers and second outer layers respectively containing oxides that differ from each other in main constituents, and boundary reaction layers are provided between the first outer layers and the second outer layers. First ceramic dielectric layers outside the boundary reaction layers differ in color from second ceramic dielectric layers inside the boundary reaction layers.
