Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a multilayer body including an inner layer portion including a plurality of main dielectric layers and a plurality of internal electrodes laminated, a first main surface and a second main surface opposed to each other in a lamination direction, a first end surface and a second end surface opposed to each other in a length direction orthogonal or substantially orthogonal to the lamination direction, a first lateral surface and a second lateral surface opposed to each other in a width direction orthogonal or substantially orthogonal to both the lamination direction and the length direction, and a pair of outer layer portions sandwiching the inner layer portion in the lamination direction;
• a first external electrode on the multilayer body;
• and
• a second external electrode on the multilayer body;
• wherein the multilayer body includes a plurality of interlayer regions each sandwiched between a corresponding one of the plurality of main dielectric layers and a corresponding one of the outer layer portions adjacent to each other in the lamination direction, and a plurality of auxiliary dielectric layers each provided in a corresponding one of the interlayer regions;
• each of the plurality of interlayer regions includes a first region located between the first end surface and a corresponding one of the plurality of internal electrodes, and a second region overlapping a corresponding one of the plurality of internal electrodes provided in a corresponding one of the plurality of interlayer regions when viewed in the lamination direction;
• each of the plurality of auxiliary dielectric layers is provided in both of the first region and the second region;
• each of the plurality of auxiliary dielectric layers provided in the first region and each of the plurality of auxiliary dielectric layers provided in the second region include a same main component of a dielectric ceramic;
• and
• each of the plurality of auxiliary dielectric layers provided in the first region and each of the plurality of main dielectric layers include different main components of a dielectric ceramic.
