Abstract
A multilayer ceramic capacitor includes a multilayer body, first internal electrode layers exposed at a first end surface of the multilayer body, and second internal electrode layers exposed at a second end surface of the multilayer body. The first internal electrode layers are exposed at a first lateral surface and a second lateral surface of the multilayer body. The second internal electrode layers are exposed at the first lateral surface and the second lateral surface of the multilayer body.

A multilayer ceramic capacitor comprising:
- a multilayer body including a plurality of dielectric layers laminated in a lamination direction, the multilayer body including a first main surface and a second main surface opposed to each other in 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 the lamination direction, and 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 and the width direction;
- first internal electrode layers on the dielectric layers and exposed at the first end surface;
- second internal electrode layers on the dielectric layers and exposed at the second end surface;
- a first external electrode including a base electrode layer disposed on the first end surface and a plated layer on the base electrode layer;
- and
- a second external electrode including a base electrode layer on the second end surface and a plated layer on the base electrode layer;
- wherein
- the first internal electrode layers are exposed at the first lateral surface and the second lateral surface;
- the second internal electrode layers are exposed at the first lateral surface and the second lateral surface;
- the first internal electrode layers each include a first region along an end thereof adjacent to the first lateral surface of the multilayer body and a second region along an end thereof adjacent to the second lateral surface of the multilayer body;
- the first region and the second region include a Ni-Mg-O phase therein;
