Patent ID: 8610526

Claim:
A coil component comprising: a resin composition containing a thermosetting resin which exists in liquid form at room temperature, a wax which exists in powder form at room temperature and has a melting point of 70 to 150° C., and a magnetic powder, the resin composition being prepared by mixing the thermosetting resin, the wax and the magnetic powder at room temperature in such a manner that the thermosetting resin and the wax are contained in the resin composition, respectively, in an amount of 40 volume % or more and in an amount of 5 to 30 volume %, and the wax and the magnetic powder are contained in the resin composition in a total amount of 10 to 50 volume %, whereby the resin composition has a viscosity of 50000 to 150000 mPa·s as measured at room temperature; and a drum core to which a winding is attached; wherein the resin composition is injected into a plurality of portions between an upper flange and a lower flange of the drum core at room temperature; and the resin composition injected into the plurality of portions of the drum core is thermally cured at a temperature greater than the melting point of the wax, thereby the wax in the resin composition is melted to provide lower viscosity to the resin composition so that the resin composition covers the entire surface of the winding.
