ABSTRACT:
A laminated ceramic capacitor includes a ceramic substrate and a plurality of internal electrodes. The ceramic substrate is of a shape defined by length, width and thickness directions. The internal electrodes are stacked one over another within the ceramic substrate at spaced intervals in the thickness direction and alternately led out to opposite ends of the ceramic substrate in the length direction. The ceramic substrate has opposite surfaces in the thickness direction, one of which is planar. In the laminated ceramic capacitor, 1<Db/Da≦2.1, where Da represents a distance between the planar surface and an outermost internal electrode at a center between the opposite ends of the ceramic substrate, and Db represents a distance between the planar surface and the outermost internal electrode at one of the opposite ends of the ceramic substrate.
