ABSTRACT:
A multilayer ceramic condenser comprises a multilayer body constituted by a plurality of dielectric layers laminated together, first and second terminal electrodes respectively positioned on opposite side faces of the multilayer body, and a plurality of inner electrode groups provided within the multilayer body in a laminating direction of the multilayer body. Each inner electrode group includes a first inner electrode connected to the first terminal electrode, a second inner electrode connected to the second terminal electrode, and a third inner electrode connected to none of the first and second terminal electrodes. The first, second, and third inner electrodes are arranged so as to hold the dielectric layer therebetween such that a plurality of capacitors connected in series are formed between the first and second inner electrodes. The number of capacitors formed in the outermost inner electrode group in the laminating direction of the multilayer body is greater than the number of capacitors formed in the inner electrode group positioned on the inner side of the outermost inner electrode group.
