PROBLEM TO BE SOLVED: To provide a flexible printed wiring board which has high adhesion with a seal member and which is less likely to be separated from the seal member.SOLUTION: A flexible printed wiring board according to the present embodiment in which a seal member is fit in an outer periphery in a width direction comprises one or a plurality of fixing holes which are provided on the seal member fitting scheduled region and penetrate in a thickness direction. The fixing holes may be dependent holes not to lead to an outer edge. Further, an opening shape of the fixing hole may be circular or oval. Further, the seal member fitting scheduled region may be formed on a curved region in a longer direction. Further, the plurality of fixing holes may be located almost symmetrically with respect to the center line in the longer direction. Further, it is preferable that the minimum diameter of the fixing hole be not less than 0.3 mm and not more than 3 mm. Further, it is preferable that a ratio of a total opening area of the one or plurality of fixing holes to an area of the seal member fitting scheduled region be equal to or smaller than 1/10.SELECTED DRAWING: Figure 1A |
