Abstract: A coil component manufacturing apparatus for winding a twisted portion of wires at a desired position of a core. A coil component manufacturing apparatus including a nozzle through which a plurality of wires can be inserted, a wire twisting mechanism that holds a core, rotates the core relative to the nozzle in a direction of twisting the wires, and forms a twisted portion in which the wires are twisted between the nozzle and the core, a wire winding mechanism that holds the core, rotates the core relative to the nozzle in a direction of winding the twisted portion is wound around the core, and winds the twisted portion around the core, and a guide member positioned closer to the core than the nozzle. The guide member guides the twisted portion to a predetermined position of the core when the twisted portion is wound around the core.

Abstract: A coil component includes an element and a coil that is provided inside the element and that is spirally wound. The coil includes a plurality of coil conductor layers and an extended conductor layer, which are laminated in a first direction.
