To provide a bending device 16 for carrying out bending of a material with good accuracy without removing the material when bending the material in a different direction.
A first bending part 27 and a second bending part 28 are arranged in a mutually eccentric state. The first bending part 27 is rotated around the center axis of the second bending part 28 while the material is arranged between both the bending parts 27, 28, so that the material is bent to one side. Next, the bending position of the material is shifted without being removed from between both the bending parts 27, 28. The second bending part 28 is rotated around the center axis of the first bending part 27, so that the material is bent to the opposite side.
