Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a multilayer body including a plurality of laminated dielectric layers and a plurality of laminated internal electrode layers, 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 effective layer portion including the plurality of dielectric layers and the plurality of internal electrode layers that are alternately laminated, and outer layer portions that sandwich the effective layer portion in the height direction;
• a first external electrode on the first end surface;
• and
• a second external electrode on the second end surface;
• wherein
• the multilayer body includes an effective layer-width direction-end portion provided at an end portion of the effective layer portion in the width direction and an effective layer-middle portion provided at a middle portion of the effective layer portion;
• the multilayer body further includes a rare earth segregation region in which a rare earth element is segregated;
• in a cross section parallel or substantially parallel to the width direction and the height direction, a relationship between a segregation amount of the rare earth element in the rare earth segregation region in the effective layer-width direction-end portion and a segregation amount of the rare earth element in the rare earth segregation region in the effective layer-middle portion is expressed as:
• the effective layer-middle portion>the effective layer-width direction-end portion;
• and
• a dielectric material of the plurality of dielectric layers includes at least one of calcium, zirconium, or strontium, and includes a perovskite structure.
