Abstract: A coil component includes a wound coil having a winding portion, having at least one turn, and a lead-out portion extending from an end portion of the winding portion to provide a separation space together with the winding portion and a body including an insulating resin and magnetic powder particles and embedding the wound coil therein. The body has a low-density portion disposed in the separation space and having magnetic powder particle density lower than average magnetic powder particle density of an entirety of the body.
