Abstract
Abstract A laminated capacitor with a plurality of capacitor units integrated therein, in which the hot-side electrode layer of a capacitor unit and the earth-side electrode layer of another capacitor unit are formed by being printed on the same surface of a dielectric layer, so that the coupling capacity between the electrodes of the capacitor units is reduced by the shielding effect of the earth-side electrodes.
