PROBLEM TO BE SOLVED: To provide a highly reliable muti-laminated ceramic capacitor which has a large effective area for internal electrodes, is free of capacitance loss, and is superior in thermal shock resistance, and a method of manufacturing the same. SOLUTION: A multi-laminated ceramic capacitor is formed by alternately laminating an internal electrode layer 2, in which each internal electrode 2a is provided with a connecting part 4 at one of the edges of each internal electrode 2a and a dielectric ceramic layer 1 repeatedly to form a plurality of laminated layers which are sintered. In the sintered body, in which a plurality of capacitor elements are integrated side by side, pairs of outer electrodes 5 are formed on the opposed side surfaces, wherein the number of pairs corresponds to the number of the capacitor elements. The edge of each connecting part 4 is exposed on the respective opposed outer surface alternately on every other layer across each dielectric layer in the laminated direction, and the internal electrodes 2a are electrically connected to respective outer electrodes 5 via exposed edges of the connecting parts 4. Here, the widths of the inner electrodes 2a, connecting parts 4 and outer electrodes 5 are such that they satisfy those relation: inner electrode 2a > outer electrode 5 > connecting part 4, and the film thickness of the connecting parts 4 is larger than that of the internal electrodes 2a, and moreover the connecting boundary part between the inner electrode 2a and the connecting part 4 are constituted of circular arc shapes 6.
