Provided is a film mirror which does not cause an ultraviolet absorbing agent to bleed out even when used as a film mirror for a solar thermal power generator over a long period of time in harsh environments, can sufficiently minimize the drop in specular reflectance, is light weight and flexible, reduces manufacturing costs, can be increased in area and mass produced, exerts excellent adhesive properties and resistance to weather and thermal shock, and has a superior specular reflectance rate against sunlight. Also provided are a method for producing said film mirror, and a reflecting device for a solar thermal generator using said film mirror. The film mirror is provided, on a resin substrate, with an ultraviolet absorbing layer and a reflective layer comprising a metal, wherein: the ultraviolet absorbing layer is configured from an ultraviolet absorbing layer comprising a polymeric ultraviolet light absorber; or the reflective layer configured from the metal functions as the silver reflective layer, and the ultraviolet absorbing layer is configured from ultraviolet absorbing layer (1) containing an ultraviolet absorber, and ultraviolet absorbing layer (2) containing an ultraviolet absorber capable of preventing silver from corrosion. |
