Abstract: Disclosed is a nano-fiber spinning apparatus using centrifugal force which includes: (i) a top plate 6c which has nano-fiber spinning holes h, and is slantly formed at an inclination angle ? with a virtual horizontal line connecting top of a side wall 6b in a disk shape; (ii) a bottom plate 6a having a curved surface which is concaved and inclined upwardly in a dish shape; and (iii) the cylindrical side wall 6b connecting the top plate 6c and the bottom plate 6a, so as to be wholly formed in a spin-top shape. Also, disclosed is a method of manufacturing nano-fibers which includes, after supplying a spinning dope to the above nano-fiber spinning apparatus 6, spinning nano-fibers with centrifugal force toward a collector 7 provided above the apparatus while generating an air flow toward the collector by an air generator provided below the nano-fiber spinning apparatus 6.
