<P>PROBLEM TO BE SOLVED: To provide a friction pressure welding method which prevents a burr from being generated at an outer surface of a joining part during friction pressure welding and enables a high joining strength not lower than the one at a part other than the joining part by simple pressure control. Ž<P>SOLUTION: In the friction pressure welding method, a pressure welding part of a joining member having at least the hollow pipe-shaped pressure welding part 10 and a pressure welding part of a joining part having at least the solid rod-like pressure welding part 20 are pressed while being relatively rotated with each other in a state that they are mutually abutted, and the joining members are pressure welded by allowing the pressure welding parts to be softened and plastically deformed and turned into a liquid phase through the friction heat. The pipe-shaped pressure welding part 10 and the rod-like pressure welding part 20 are relatively rotated to be abutted with each other in a storage space 31 of a fixture 30 which has an inner diameter slightly larger than an outer diameter of the pipe shaped pressure welding part 10 and the rod-like pressure welding part 20 and has the storage space 31 having both ends that are opened.
