ネジアンカーにもなる。An embodiment of the present invention will be described below with reference to FIG. In the manufacturing method according to the present embodiment, first, the reinforcing bar 1 is cut to a required length. On the other hand, a joint member having a female screw portion (a blind hole nut) 3 is prepared on a round bar (a hexagonal high nut or the like), and the two are joined by friction welding. The joint of the rebar produced in this manner is very firmly joined because the joints are joined by friction welding. This joint also serves as a female screw anchor that enters the concrete in addition to the joint.
