MULTILAYER CERAMIC CAPACITOR AND MOUNTING STRUCTURE OF MULTILAYER CERAMIC CAPACITOR

To provide a multilayer ceramic capacitor that suppresses occurrence of "squealing," without significantly impairing profile thinning (downsizing) and capacity heightening.SOLUTION: A multilayer ceramic capacitor includes a laminate in which a plurality of dielectric layers 20 and a plurality of internal electrode layers 30 are laminated. When it is assumed that, out of the plurality of internal electrode layers 30, an internal electrode layer that is located on a first surface TS1 side is defined as a first surface-side internal electrode layer 301 and an internal electrode layer that is located on a second surface TS2 side is defined as a second surface-side internal electrode layer 302, a first solid solution layer 301A where a second metal different from a first metal that is a main component is dissolved is formed at an interface, with the dielectric layer 20, of the first surface-side internal electrode layer 301, and a second solid solution layer 302A where the second metal is dissolved is formed at the interface, with the dielectric layer 20, of the second surface-side internal electrode layer 302. Concentration of the second metal in the second solid solution layer 302A is greater than concentration of the second metal in the first solid solution layer 301A.SELECTED DRAWING: Figure 4 【課題】薄型化（小型化）および高容量化を大きく損なうことなく、「鳴き」の発生を抑制する積層セラミックコンデンサを提供する。【解決手段】積層セラミックコンデンサは、積層された誘電体層２０および内部電極層３０を含む積層体を備える。内部電極層３０のうち、第１面ＴＳ１側に配置されている内部電極層を第１面側内部電極層３０１とし、第２面ＴＳ２側に配置されている内部電極層を第２面側内部電極層３０２とすると、第１面側内部電極層３０１は、誘電体層２０との界面に、主成分の第１の金属と異なる第２の金属が固溶した第１の固溶層３０１Ａを含み、第２面側内部電極層３０２は、誘電体層２０との界面に、第２の金属が固溶した第２の固溶層３０２Ａを含む。第２の固溶層３０２Ａにおける第２の金属の濃度は、第１の固溶層３０１Ａにおける第２の金属の濃度よりも高い。【選択図】図４
