Beschreibung
Zusammenfassung:	[PROBLEM] To produce nanofiber sheets that are homogeneous over the entire surface of the sheets. Furthermore, to prevent a polymer solution that fails to become nanofibers in a fiber generation device from turning into droplets or small polymer masses that fly straight toward a nanofiber collection device, thereby avoiding directly hitting a nanofiber collecting surface of the nanofiber collection device.[SOLUTION] A nanofiber production apparatus provided with: a nanofiber generation device equipped with a liquid discharge nozzle for discharging a polymer solution in which a polymer has been dissolved in a solvent, and a hot air discharge nozzle for discharging a high-temperature, high-speed gas at high pressure; and a collection device for suctioning and collecting nanofibers generated by the nanofiber generation device. A flow path suppression means is provided between the nanofiber generation device and the nanofiber collection device, said flow path suppression means causing the nanofibers generated by the nanofiber generation device to float so that the flow of nanofibers generated by the nanofiber generation device do not directly fly straight into the nanofiber collection device.
