Zusammenfassung:In a manufacturing method in which an aluminum bullet is extruded to obtain an extruded raw pipe 4 and then the extruded raw pipe 4 is subjected to a drawn process, the aluminum extruded raw pipe 4 is cut at a position within 10 m from a discharge position M of an extruding die to obtain an aluminum extruded raw pipe 4 with a length of 10 m or shorter, and the extruded raw pipe 4 is subjected to a drawing process. With this, an aluminum pipe excellent in surface quality having no surface defect such as white peeling can be manufactured at high manufacturing efficiency.
