Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adsorption nozzle capable of conveniently and exactly adsorbing a molding preform without scratching the surface of the molding preform, and to provide a device for transferring the molding preform by which the molding preform can stably be transferred by using the adsorption nozzle. SOLUTION: The adsorption nozzle 1 which vacuum-adsorbs the molding preform for optical element formed on a reception mold comprises: a cover body 2 capable of forming a closed space by covering a reception surface from an above part of the reception mold; a suction port 3 capable of vacuum-adsorbing the molding preform for optical element formed on the reception surface; and an external air introduction port 4 capable of sucking external air into the closed space.
