PROBLEM TO BE SOLVED: To provide a flexible printed wiring board excellent in noise resistance and capable of preventing moisture intrusion into the inside of electronic equipment.SOLUTION: A flexible printed wiring board according to one embodiment comprises at least a conductive pattern of at least one layer, an insulating film disposed on both surface sides of the conductive pattern and having flexibility, an electromagnetic wave shield film disposed in at least a part of an outer surface of the insulating film, and a seal member having a through hole through which the conductive pattern and the insulating film are inserted. An inner surface of the through hole of the seal member abuts against an outer surface of the insulating film. In the outer surface of the insulating film, the electromagnetic wave shield film may be disposed apart from the seal member. An average width of the separation region between the electromagnetic wave shield film and the seal member is preferably not less than 0.5 mm and not more than 2.5 mm. The separation region between the electromagnetic wave shield film and the seal member may be formed on both sides of the through hole.SELECTED DRAWING: Figure 2 |
