Abstract
A multilayer ceramic capacitor includes a laminate including a dielectric ceramic layer and first and second internal electrode layers laminated in a lamination direction, and first and second external electrode connected to the internal electrode layers. The laminate includes a central layer portion, a peripheral layer portion sandwiching the central layer portion, and a side margin sandwiching the central layer portion and the peripheral layer portion. The side margin including an inner layer and an outer layer. In a cross section including a lamination direction and a width direction obtained by cutting the laminate at a central portion in a length direction, Si is segregated in an inner region including the inner layer and a boundary between the inner layer and the central layer portion, and a Si segregation spot in the inner region has a larger area than a Si segregation spot in the outer layer.
