Résumé dans la langue de publication, traduction non disponible Signal wires (14) are attracted into and held by a suction nozzle (20), and the signal wires (14) are positioned to desired positions in this holding state then they are fixed to a circuit board. As a result, the suction nozzle (20) attracts the signal wires (14) along with the air and easily hold them even if distal ends of the signal wires (14) are spatially scattered, e. g., if the wires are somewhat away from the suction nozzle (20). Since the signal wires (14) are attracted into and held by the suction nozzle (20) in such manner, no excessive force is applied to the signal wires (14) above the suction force of the suction nozzle (20) and the signal wires (14) are not cut during transfer even when they are transferred in the holding state.
