Disclosed herein are coil parts including: a lower magnetic substance; a primary coil pattern disposed on the lower magnetic substance; a first complex layer for covering the primary coil pattern; a secondary coil pattern correspondingly disposed on an upper side of the primary coil pattern; a second complex layer for covering the secondary coil pattern; and an insulation layer disposed between the primary coil pattern and the secondary coil pattern and blocking an electrical connection between the primary coil pattern and the secondary coil pattern. The coil parts according to the present invention can have a simple structure and processing capable of increasing magnetic permeability and accordingly improving an impedance characteristic of the coil parts, thereby implementing excellent performance and characteristic.
