    Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers alternately laminated therein, and external electrode layers respectively provided on both end surfaces of the multilayer body in a length direction intersecting a lamination direction, and each connected to the internal electrode layers, the external electrode layers each further including a base electrode layer including a first region, a second region, and a third region divided therein, in order from the multilayer body. The first region includes a metal included in the internal electrode layers in a higher amount than the second region and the third region, the second region includes glass in a higher amount than the first region and the third region, and the third region includes copper in a higher amount than the first region and the second region.

    Abstract: A multilayer ceramic capacitor includes a multilayer body including an inner layer portion including internal electrode layers and inner dielectric layers laminated alternately, and internal electrode layers at both ends thereof in a lamination direction, and outer dielectric layers covering the inner layer portion, and two external electrodes on both end surfaces of the multilayer body in a length direction intersecting the lamination direction. The inner and outer dielectric layers each include grains, and a difference between an average grain size of grains in the inner dielectric layers and an average grain size of grains in the outer dielectric layers is about 100 nm or less.

    Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers, and external electrodes. The multilayer body includes side margin portions made of a dielectric. In the internal electrode layers, a width of an extension electrode portion is smaller than a width of a counter electrode portion. The side margin portions each include Ba and Ti as a main component and Mg as a sub component. The Mg content is about 0.2 mol% or more and about 2.0 mol% or less with respect to 100 mol of Ti. The internal electrode layers each include Ni as a main component, and an end portion of the counter electrode portion includes Mg as a sub component. The Mg content is about 0.13 mol% or more and about 0.39 mol% or less with respect to 100 mol of Ni.

    Abstract: A multilayer ceramic capacitor includes a laminate including a dielectric ceramic layer and first and second electrode layers laminated in a lamination direction, and first and second external electrodes respectively connected to the first and second internal electrode layers. The laminate includes a central layer portion, a peripheral layer portion sandwiching the central layer portion, and a side margin sandwiching the central layer portion and the peripheral layer portion. The first and second internal electrode layers and the first and second external electrodes include Ni. In a cross section including the lamination direction and a width direction, a Ni content of the peripheral layer portion is larger at a surface portion than at a central portion in a thickness direction, and a Ni content of the side margin is larger at a surface portion than at a central portion in a thickness direction of the side margin.
