To provide a coil component for noise removal.
This invention discloses a coil component including: a lower magnetic body; a first coil pattern provided on the lower magnetic body; a first composite layer covering the first coil pattern; a second coil pattern provided so as to correspond to the upper side of the first coil pattern; a second composite layer covering the second coil pattern; and an insulation layer disposed between the first coil pattern and the second coil pattern and interrupting the electric connection between the first coil pattern and the second coil pattern. According to this invention, the magnetic permeability and the impedance characteristics are improved with an easy structure and process. Thus, the coil component achieving excellent performance and having excellent characteristics is realized.
