Multilayer ceramic capacitor, multilayer ceramic capacitor series including the same, and multilayer ceramic capacitor mount body including the same

A multilayer ceramic capacitor comprising:

• a body that includes a plurality of dielectric layers and a plurality of conductive layers stacked on each other in a stacking direction and that includes first and second main surfaces opposing each other in the stacking direction, first and second end surfaces opposing each other in a length direction and connecting the first and second main surfaces, and first and second side surfaces opposing each other in a width direction and connecting the first and second main surfaces and the first and second end surfaces;
• and
• first and second outer electrodes that are disposed on portions of a surface of the body;
• wherein
• the body includes a first outer layer portion including a first of the plurality of dielectric layers defining the first main surface, a second outer layer portion including a second of the plurality of dielectric layers defining the second main surface, and an inner layer portion adjacent to both of the first outer layer portion and the second outer layer portion, the inner layer portion includes a portion extending from a first outermost conductive layer positioned closest to the first main surface among the plurality of conductive layers through a second outermost conductive layer positioned closest to the second main surface among the plurality of conductive layers in the stacking direction;
• a dimension of the body in the stacking direction is smaller than a dimension of the body in the width direction;
• the second outer layer portion includes an outer portion including the second main surface and an inner portion adjacent to both of the outer portion and the inner layer portion;
• and
• the outer portion includes a boundary region adjacent to the inner portion which has a larger Si content compared to a central region of the outer portion.
