Claims

[Scope of utility model registration request]

A hole is provided in an unnecessary part of the curved bent portion of the flexible printed circuit board through which the conductive pattern does not pass, and an arm portion having a length approximately twice the length of the bent radius is provided in the hole to protrude in the longitudinal direction. The part is bent at a right angle and its tip is fixed at a position opposite to the base of the arm after the printed circuit board is bent, and the position of the arm is changed from the top edge of the bent part to the arm when the printed circuit board is bent. A flexible printed circuit board characterized in that the distance to the end face near the bent part of the part is located at a position where the distance is approximately the radius length.
