Abstract
A multilayer ceramic capacitor includes a laminate including a dielectric ceramic layer and first and second electrode layers laminated in a lamination direction, and first and second external electrodes respectively connected to the first and second 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 first and second internal electrode layers and the first and second external electrodes include Ni. In a cross section including the lamination direction and a width direction, a Ni content of the peripheral layer portion is larger at a surface portion than at a central portion in a thickness direction, and a Ni content of the side margin is larger at a surface portion than at a central portion in a thickness direction of the side margin.
