Abstract
A multilayer ceramic capacitor that includes dielectric layers made mainly of a perovskite compound containing Ba and Ti and optionally Zr and Hf, and inner electrodes having an average thickness of approximately 0.5 μm or less. The Mg content of the dielectric layers is approximately in the range of 0≦Mg≦0.4 (parts by mole) based on a total of 100 parts by mole of Ti, Zr, and Hf. The proportion of Mg-containing defects in the inner electrodes is approximately 20% or more.
