Abstract
An electronic component includes: a body including a coil part disposed therein and containing magnetic metal particles; and a surface protection layer disposed on a surface of the body. The magnetic metal particles comprise two or more kinds of particles having different particle sizes from each other, a portion of the magnetic metal particles are exposed to the surface of the body, and uneven regions are formed on the regions of the surfaces of the magnetic metal particles exposed to the surface of the body, and the surface protection layer is in contact with the uneven regions.
