Abstract: A coil component includes: a body including a magnetic material and a coil of which both ends are externally exposed; intermetallic compounds disposed on the exposed both ends of the coil; and external electrodes disposed on the body to cover the intermetallic compounds. The external electrodes include: conductive resin layers disposed on outer surfaces of the body to contact the exposed both ends of the coil and including base resins, a plurality of metal particles disposed in the base resins, and conductive connecting parts surrounding the plurality of metal particles and contacting the intermetallic compounds. The coil component further includes electrode layers disposed on the conductive resin layers and contacting the conductive connecting parts.
