Abstract
In an embodiment, a multilayer ceramic capacitorhas a first external electrodeand a second external electrodethat each contain metal grains MP and dielectric grains DP, where an oxide of the same metal element constituting the metal grain MP, or MO, is present at the interface between the metal grain MP and the dielectric grain DP. The multilayer ceramic capacitor can prevent the hardness of its external electrodes from dropping, even when the external electrodes contain metal grains and dielectric grains.
