Abstract

The present inventive concept relates to a composite element, which includes a stacked body in which a plurality of sheets are stacked, a plurality of first noise filter portions capable of generating a first resonance frequency and provided in the stacked body, each first noise filter portion including one or more coil patterns, a second noise filter portion capable of generating a second resonance frequency higher than the first resonance frequency, provided in the stacked body, and including a capacitor and an inductor, a plurality of external electrodes provided outside the stacked body and connected to the plurality of first noise filter portions and a part of the second noise filter portion, and a ground electrode provided outside the stacked body and connected to a part of the second noise filter portion, and can expand the band of frequencies at which noise can be removed and adjust the resonant frequency for removing noise.
