Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a multilayer body including dielectric ceramic layers and internal electrode layers laminated in a lamination direction;
• and
• external electrodes connected to the internal electrode layers;
• wherein
• the multilayer body includes a first main surface and a second main surface opposed to each other in the lamination direction, a first side surface and a second side surface opposed to each other in a width direction perpendicular or substantially perpendicular to the lamination direction, and a first end surface and a second end surface opposed to each other in a length direction perpendicular or substantially perpendicular to the lamination direction and the width direction;
• the multilayer body includes a segregation including Si as a main component in a vicinity of an end of the internal electrode layer in the width direction;
• and
• an average particle size of dielectric particles in the vicinity of the end of the internal electrode layer in the width direction in the dielectric ceramic layer is smaller than an average particle size of dielectric particles in a central portion of the internal electrode layer in the width direction in the dielectric ceramic layer.
