Abstract: A nanofiber producing apparatus 10 includes a spinning solution jetting means 11 having a conductive nozzle 13 for jetting a stock spinning solution for nanofiber production, an electrode 14 located away from the nozzle 13, a voltage generating means 101 generating a voltage between the nozzle 13 and the electrode 14, an air jetting means 15 located at such a position as to direct an air jet between the nozzle 13 and the electrode 14, and a nanofiber collecting means. The voltage generating means 101 generates a voltage so that the nozzle 13 serves as a positive pole and the electrode 14 as a negative pole. The electrode 14 is covered, on almost the entire area of its side facing the nozzle 13, with a covering 17 having a dielectric exposed on the surface thereof. The dielectric exposed on the surface of the covering has a thickness of 0.8 mm or greater.
