By being bent while being held by the bending member 1, the repulsive force against bending is suppressed by the holding parts 7A, 7B, and the holding parts 7A, 7
It is held along the bent shape of B. In addition, in the bending process of the flexible printed circuit board 11, it is possible to set the radius of curvature of the bent portion within the range of elastic deformation of the flexible printed circuit board 11, thereby preventing heating or excessive deformation of the flexible printed circuit board 11. It is possible to bend the flexible printed circuit board 11 without applying any
The flexibility of the flexible printed circuit board 11 other than the bent portions is not impaired. In addition, since the bending member 1 is provided with the notch 5 in the bending portion 6, stress is concentrated on the bending portion 6 when folding in half, making it easier to bend, and the bending member 1 can be folded across the notch 5.
