1. A coil component, comprising:
a body having a first surface and a second surface opposing each other and a plurality of wall surfaces connecting the first surface to the second surface, and including insulating resin and magnetic metal powder particles;
an insulating substrate disposed in the body;
a coil portion disposed on the insulating substrate and including a lead-out pattern exposed to a first wall surface of the plurality of wall surfaces of the body; and
an external electrode disposed on the body and connected to the lead-out pattern,
wherein each of the plurality of wall surfaces of the body has at least one of the magnetic metal powder particles exposed thereto,
wherein the at least one of the magnetic metal powder particles exposed to the first wall surface of the body has a cut-out surface, and
wherein the at least one of the magnetic metal powder particles exposed to a second wall surface connected to the first wall surface of the plurality of wall surfaces of the body does not have a cut-out surface.
