Abstract
A multilayer ceramic capacitor includes a multilayer body and an outer electrode. The multilayer body includes dielectric layers and inner electrode layers alternately stacked with the dielectric layers. Ni in one of first and second inner electrode layers forms a solid solution with Pt, and Ni in the other of the first and second inner electrode layers forms no solid solution with Pt. The one of the first and second inner electrode layers in which Ni forms a solid solution with Pt are coupled to a cathode when the multilayer ceramic capacitor is mounted.
