Abstract: A coil component includes a body, a coil part embedded in the body, and an insulating layer covering the body. First and second plating electrodes are disposed between the body and the insulating layer, are connected to the coil part, and are disposed to be spaced apart from each other on one surface of the body. First and second through electrodes penetrate through the insulating layer to thereby be connected to the first and second plating electrodes, respectively.
