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.

Abstract: Disclosed herein is a method of manufacturing a coil, including: preparing a mold having vertically movable fixing pins disposed therein and slidable left and right sidewalls; seating a magnetic plate on an inner bottom of the mold; loading the coil on the magnetic plate so that lead parts of the coil are disposed between the fixing pins and the sidewalls of the mold; sliding the left and right sidewalls of the mold into the mold to closely adhere the lead parts of the coil to the fixing pins; filling a magnetic slurry in the mold and primarily pressing the magnetic slurry; and lowering the fixing pins to perform secondary pressing, in order to prevent deformation or position deviation of the coil at the time of molding the coil.
