PURPOSE:To improve the withstand voltage performance of a capacitor by providing a float electrode layer connected to neither of the internal and external electrodes at positions corresponding to the periphery of the ends of the internal electrodes in a dielectric layer between the internal electrodes when the dielectric layer and the internal electrode layers are laminated to provide a capacitor. CONSTITUTION:A dielectric layer 1 made of alumina, mullite, steatite, etc., and an internal electrode layer 2 made of gold, silver, copper, nickel, etc., are laminated, external electrodes 3 are attached to both end faces of its laminate, thereby providing a laminated ceramic capacitor. In this structure, the internal electrode layers 2, 2' are alternately connected to external electrode layers 3. In this case, floating electrodes 4 disposed in the layer 1 corresponding to the periphery of the ends of the electrodes 2, 2', connected to neither of the electrodes 2, 2' and 3 in a short length and made of the same material are provided in parallel. Thus, a dielectric breakdown voltage can be enhanced without altering the interval of the electrodes, 2, 2', thereby reducing the size of the capacitor.
