Abstract
A coil component includes a body having one surface and the other surface opposing each other and including a magnetic metal powder particle and an insulating resin; a coil portion embedded in the body and having end portions respectively exposed from end surfaces of the body; first and second external electrodes arranged to be spaced apart from each other on the one surface and extending to the end surfaces to be connected to the end portions, respectively; and an external insulating layer disposed between each of the first and second external electrodes and the one surface of the body. A magnetic metal powder particle exposed on the wall surface of the body, among the magnetic metal powder particle, has a plating prevention film disposed on at least a portion of a surface of the exposed magnetic metal powder particle and including metal ions of the magnetic metal powder particle.
