ABSTRACT:
A monolithic ceramic capacitor includes a plurality of stacked ceramic dielectric layers, thin internal conductors that are each placed between the ceramic dielectric layers and arranged in parallel, and external conductors each electrically connected to ends of the corresponding internal conductors. The ceramic dielectric layers have a thickness of about 0.5 μm to less than about 1.5 μm. The internal conductors have a thickness of about 0.1 μm to about 0.4 μm. The internal conductors each have spaces therein and the total area percentage of the spaces in each internal conductor is more than about 10% to less than about 40% of the area of the internal conductor. The ceramic dielectric layers contain a sintering additive containing Si, and the sintering additive is placed in the spaces in a segregated manner.
