Abstract
A laminated ceramic capacitordivided into a first laminatea second laminatea third laminateand a fourth laminateThe first laminateincludes a ceramic layerserving as a dielectric layer. The ceramic layeris thicker than a ceramic layersandwiched between internal electrodesin the second laminateor the fourth laminateand thinner than 20 times the thickness of the ceramic layerThe third laminateincludes dielectric layers, which serve as the ceramic layersand has a thickness of 5% of the total thickness of the second laminateand the fourth laminateAccordingly, the third laminateachieves the function of absorbing an electrode-induced thickness differential. Also, by means of regulating the thickness of the first laminateportions of via electrodesthat extend without being electrically connected to the internal electrodescan be shortened.
