    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).

    Abstract: A component built-in substrate includes a multilayer body and a substrate including a multilayer ceramic electronic component embedded therein. The multilayer ceramic electronic component includes a first connection portion that protrudes from the first external electrode, and a second connection portion that protrudes from the second external electrode. The substrate includes a core material. The multilayer ceramic electronic component including the first connection portion and the second connection portion includes a surface covered by the core material and embedded in the substrate. The first connection portion protrudes toward a surface of the substrate, and is not exposed at the surface of the substrate. The second connection portion protrudes toward the surface of the substrate, and is not exposed at the surface of the substrate.
