1. A coil component comprising:
a wound coil having a winding portion including a plurality of turns and a lead-out portion extending from an end portion of the winding portion to provide a separation space, together with the winding portion, the wound coil including a metal wire having a surface on which an insulating coating portion is disposed, wherein each of the plurality of turns of the winding portion includes an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface to each other;
a body embedding the wound coil therein and including magnetic powder particles and an insulating resin; and
an insulating layer disposed on at least one of the side surface of an outermost turn of the plurality of turns of the winding portion and a surface of the lead-out portion providing the separation space,
wherein the insulating layer is spaced apart from the side surface of one inner turn of the plurality of turns of the winding portion facing the side surface of another inner turn of the plurality of turns of the winding portion, and
the insulating coating portion covers the side surface of the one inner turn of the plurality of turns of the winding portion facing the side surface of the another inner turn of the plurality of turns of the winding portion, and also covers the upper surface or the lower surface of the one inner turn of the plurality of turns of the winding portion.
