PROBLEM TO BE SOLVED: To provide a device for consecutively manufacturing a spirally corrugated metal tube capable of manufacturing a shorter pitched wave tube, especially a shorter tube having an outside diameter of not more than 6 mm by improving the conventional device. SOLUTION: The device for consecutively manufacturing the spirally corrugated metal tube is characterized in that the device manufactures consecutively the spirally corrugated tubes (12, 14) composed of a corrugated head (11) rotatably driven so that a corrugated chemical engineering implement (16) is supported internally so as to freely rotate eccentrically against long axes of the metal tubes (12, 14) and the corrugated chemical engineering implement (16) is at least a round plate, and an eccentric position of the round plate against the long axes of the metal tubes (12, 14) can be adjustable and the round plate rolls on the metal tubes (12, 14) together with its circumferential surface.
