Disclosed are a nanofiltration composite hollow fiber membrane and a method of manufacturing the same. The nanofiltration composite hollow fiber membrane includes a reinforcement (1) which is a tubular braid, a polymeric resin thin film (2) coated on the outer surface of the reinforcement (1), and a polyamide active layer (3) formed on the outer surface of the polymeric resin thin film. The present invention has an advantage of an excellent strength and an increase in membrane area relative to an installation area.
