Abstract
A core bar for bending of a pipe and a method of bending of a pipe are provided whereby collapse of the pipe can be prevented and bending can be automated at low cost. Ends of the respective core bar portions are formed such that, when the ends of the two cylindrical core bar portions are engaged telescopically, and one core bar portion is bent at a desired angle with respect to the other core bar portion, the outside circumferential surface of the bending region that is formed by these core bar portions becomes a curved surface along the generating line.
