Coil component and board having the same
A coil component includes a magnetic body including first and second coil patterns disposed on first surfaces of two substrates spaced apart from each other and third and fourth coil patterns disposed on second surfaces of the two substrates, respectively, the substrates having respective cores; and first to fourth external electrodes disposed on outer surfaces of the magnetic body and connected to the first to fourth coil patterns, respectively. A gap member is disposed between the two substrates and in a central portion of the magnetic body in a thickness direction thereof.
