Abstract
Internal electrodes 21 to 27 overlap one another in the direction of thickness T via dielectric ceramic layers 10 inside a dielectric ceramic body 1, with alternate ends of adjacent internal electrodes connected to the pair of external terminal electrodes 31 and 32 at alternate sides in the lengthwise direction L. The ends of the internal electrodes 21 to 27 at the other side in the lengthwise direction L extend into the areas enclosed by the external terminal electrodes 31 and 32, with the two corner portions of each internal electrode at the opposite side in the widthwise direction W cut off. The corner portions are cut off to ensure that corner portion areas of the internal electrodes that would otherwise be contained within a triangular area S11 formed by the shortest hypothetical line X11 connecting the middle point of the external terminal electrode 31 viewed in the widthwise direction W and a front end 321 of the external terminal electrode 32 viewed in the lengthwise direction L, one surface in the widthwise direction W and one surface in the lengthwise direction L of the dielectric ceramic body 1 are removed.
