Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a plurality of dielectric layers and a plurality of internal electrode layers that are laminated, a first main surface and a second main surface opposed to each other in a height direction, a first lateral surface and a second lateral surface opposed to each other in a width direction orthogonal or substantially orthogonal to the height direction, a first end surface and a second end surface opposed to each other in a length direction orthogonal or substantially orthogonal to the height direction and the width direction, an inner layer portion in which the plurality of dielectric layers and the plurality of internal electrode layers are alternately laminated, and outer layer portions sandwiching the inner layer portion between the first main surface and the second main surface;
• a first external electrode on the first end surface;
• and
• a second external electrode on the second end surface;
• wherein
• when an internal electrode layer of the plurality of internal electrode layers closest to one of the outer layer portions is defined as an outermost internal electrode layer, in a cross section parallel or substantially parallel to the length direction and the height direction, the outermost internal electrode layer includes an internal electrode existing region and an internal electrode dividing region;
• the internal electrode dividing region includes a segregated region of magnesium or manganese;
• and
• a ratio B/A of a distance B in the length direction of the segregated region of magnesium or manganese relative to a distance A in the length direction of the internal electrode existing region is about 50% or more and about 75% or less.
