PROBLEM TO BE SOLVED: To effectively prevent the reflection of a flexible printed-circuit board in order to prevent a flare, a ghost or the like due to the reflection of leakage light caused by the flexible printed-circuit board used for a signal transmission means in the interior of a camera. SOLUTION: An antireflection layer in which synthetic-resin fine particles in an average particle size of 15 to 50 μm and carbon-black fine particles in an average particle size of 1.0 μm or lower are dispersed into 10 pts.wt. of a synthetic-resin binder such that their ratio is a weight ratio of 1:0 to 1:5 and that their total amount becomes 20 to 500 pts.wt. is formed, or a film, for antireflection, which comprises the antireflection layer is pasted, on a part or the whole of a flexible printed-circuit board. |
