1. A multilayer capacitor comprising:
an element body formed of dielectric ceramic; a plurality of internal electrodes disposed inside the element body such that the internal electrodes are stacked with ceramic layers sandwiched therebetween; and a pair of terminal electrodes provided on an outer surface of the element body and connected to the internal electrodes, wherein: a capacitor area which includes the plurality of internal electrodes and a suppression area for reducing electrostriction caused by the plurality of internal electrodes to suppress noise are formed, at least part of the suppression area is adjacent to the capacitor area, a thickness of the suppression area is determined according to an arrangement of the plurality of internal electrodes, the thickness being determined to satisfy the following expressions:
α/β≦650α=We*n/d (We: electrode width, n: number of stacked electrodes, d: inter-electrode distance); andβ=T/W (T: suppression area thickness, W: element body width), a marking for indicating a position of the capacitor area relative to the element body is provided on the outer surface of the element body, and the marking is formed by wiring out a plurality of marking internal electrodes to the outer surface at a portion where the paired terminal electrodes are not formed, the marking is integrated with ends of the plurality of marking internal electrodes exposed in the outer surface. |
