Patent attributes
A capacitor body includes a capacitance-forming section including an alternately arranged plurality of internal electrodes and plurality of dielectric ceramic layers and outer layer sections disposed on the upper or lower face of the capacitance-forming section (28). The outer layer sections include an outermost layer and a second layer (31) inwardly located therefrom. The second layer has a thermal expansion coefficient greater than that of the outermost layer by 1×10−6/° C. to 3×10−6/° C. The outermost layer has a thickness of 50 to 80 μm. The second layer has a thickness of 20 to 50 μm. The arrangement prevents cracks from being formed in a monolithic ceramic capacitor when external electrodes are formed by baking and cooling, and cracks caused by fatigue failure due to low-stress cycles such as heat cycles are prevented from reaching internal electrodes.
