Disclosed arc: a film mirror which can have a satisfactorily reduced regular reflectance even when used as a film mirror for solar power generation purposes under severe environments for a long period, is lightweight and flexible, can be produced at a reduced cost, has an enlarged surface area, can be produced on a large scale, has excellent light resistance and weather resistance, and has a good regular reflectance to solar light; a process for producing the film mirror; and a reflection device for solar power generation purposes, which is equipped with the film mirror. The film mirror is characterized by comprising a resin base, a silver reflective layer, and a layer containing an ultraviolet ray absorber, wherein at least one component contained in the ultraviolet ray absorber fulfills the requirement represented by formula (1): Aa ‰¥ 1.2×Ab (wherein Aa represents the absorbance at a peak having an absorption maximum at a wavelength of 260 to 320 nm; and Ab represents the absorbance at a peak having an absorption maximum at a wavelength of 321 to 400 nm).
