1. A coil component manufacturing apparatus comprising:
a nozzle configured to receive a plurality of wires;
a wire twisting mechanism configured to hold a core, rotate the core-relative to the nozzle in a direction of twisting the plurality of wires, and form a twisted portion in which the plurality of wires are twisted between the nozzle and the core;
a wire winding mechanism configured to hold the core, rotate the core relative to the nozzle in a direction of winding the twisted portion around the core, and wind the twisted portion around the core; and
a guide positioned closer to the core than the nozzle, the guide being configured to guide the twisted portion to a predetermined position of the core when the twisted portion is wound around the core.
