Disclosed are: a flm mirror for use in the generation of a solar power, in which the reduction in a regular reflection factor (which is caused by the deterioration in an adhesive layer arranged on a side opposite to the light incidence side of a reflective layer) can be prevented, and which is lightweight, has excellent flexibility, light resistance and weather resistance and also has a good regular reflection factor to solar light; a process for producing the film mirror; and a reflecting device for use in the generation of a solar power, which comprises the film mirror. The film mirror for use in the generation of a solar power is characterized by comprising: a silver alloy reflective layer which can reflect light having a wavelength of 320 nm at a reflectivity of 39% or more and contains a typical metal element or a transition metal element in an amount of 0.1 to 10 mass % inclusive; or both a silver layer and a reflective layer which is laminated on a side opposite to the light incidence side of the silver layer at a thickness of 5 nm to 50 µm inclusive, can reflect light having a wavelength of 320 nm at a reflectivity of 39% or more, and comprises a typical metal element or a transition metal element. The mirror film is also characterized by additionally comprising an adhesive layer which is arranged on a side opposite to the light incidence side of the silver alloy reflective layer or the reflective layer and is to be adhered onto the substrate. |
