The present invention relates to a nozzle for manufacturing a polymeric hollow fiber membrane. A plurality of vertical grooves are formed on the outer circumferential surface of an inner case, and polymers move downward along the grooves, between the inner case and an outer case, and are dispersed and discharged. Thus, the manufacturing of the nozzle is simple, and the durability of the nozzle can be enhanced. By evenly discharged polymers, the thickness and density of the hollow fiber can be constantly maintained. |
