A coil part is provided. The coil part includes a coil layer, a lower magnetic layer, and an upper magnetic layer. The coil layer includes a primary coil pattern, a secondary coil pattern, and a dielectric including the primary coil pattern and the secondary coil pattern. The lower magnetic layer is disposed under the coil layer. The upper magnetic layer is disposed on the lower magnetic layer to fill up the center and the periphery of the coil layer and cover the coil layer. Accordingly, the coil part can improve filtering characteristics by more smoothly increasing a magnetic flux surrounding the coil pattern. Also, the coil part can cut fabrication costs by reducing the length of the coil pattern with respect to the same characteristics.
