A spinning nozzle for dry spinning a spinning solution containing a metal compound and an organic polymer compound by a blowing method. In the spinning nozzle, an air nozzle 6 has a rectangular-prism-like slit which is formed by opposing inner surfaces, extending in parallel to each other, of the projecting portion, which are formed at the front side, of a pair of cover plates 1,1, each of the projecting portion having a knife edge portion at its free end. Spinning solution supplying nozzles are composed of a plurality of linear pipes and are arranged in the air nozzle 6 in such a manner that they are in parallel to the parallel surfaces of the cover plates and are projected from the edges of the parallel surfaces. Air fed through a gas feeding port 5 and blown out as an air stream from the air nozzle 6, and streams of the spinning solution extruded from the spinning solution supplying nozzles form parallel streams. Further, the air stream in parallel to the spinning solution streams is sufficiently rectified so that it becomes contact with the spinning solution. Accordingly, an amount of air used can be greatly reduced and fibers having excellent quality can be produced.
