Abstract:
A film mirror for solar radiation collection includes at least a protective layer, a silver reflective layer and a resin substrate in this order from a light incident side and has a corrosion inhibitor present at either or both of a surface and a surface layer of the silver reflective layer on the protective layer side, with the content of the corrosion inhibitor being 0.1 to 10 mg/m2. The film mirror for solar radiation collection is excellent in adhesion of the protective layer and in lightfastness as well.
