Abstract
A multilayer ceramic capacitor contains Ni in internal electrodes, and includes a sintered metal layer containing Cu in external electrodes. At a joined portion between each internal electrode and each external electrode, mutual diffusion layers of Cu and Ni extend across the internal and external electrodes. On each internal electrode, a mutual diffusion layer is present with a thickness t, which is defined by a dimension from a first end surface or a second end surface to an interior end in a longitudinal direction, not smaller than about 0.5 μm and not greater than about 5 μm. On each external electrode, a mutual diffusion layer is present with a thickness t, which is defined by a dimension from the first end surface or the second end surface to an exterior end in the longitudinal direction, not smaller than about 2.5% and not greater than about 33.3% of a thickness tof a sintered metal layer.
