Abstract: A coil component includes a core including a winding core portion and a first flange portion that is disposed on a first end portion of the winding core portion in a direction in which the winding core portion extends. A first curved portion is formed at a connection between a bottom surface of the winding core portion and the first flange portion. A ratio of a length of the first curved portion in a height direction to a distance in the height direction between the bottom surface and a first terminal electrode is no less than 20% and no more than 60% (i.e., from 20% to 60%).

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.
