A multi-layer ceramic capacitor is constituted by ceramic dielectric layers alternately laminated with conductive layers, wherein the ceramic dielectric layers are sintered in such a way that core-shell grains having a core-shell structure are mixed with uniform solid-solution grains resulting from uniform progression of the solid solution process. Such multi-layer ceramic capacitor is characterized in that the area ratio of the core-shell grains to all sintered grains constituting the ceramic dielectric layer is 5 to 15% and that the average grain size of all sintered grains including the core-shell grains and uniform solid-solution grains is 0.3 to 0.5 μm. |
