FILM MIRROR, FILM MIRROR FOR SOLAR THERMAL POWER GENERATION, AND REFLECTION DEVICE FOR SOLAR PHOTOVOLTAIC POWER GENERATION

摘要

Disclosed is a film mirror wherein a silver reflective layer is provided on at least one surface of a resin base and a layer, which has an electrical resistance of from 1.0 × 10^-3 to 1.0 × 10⁹ Ω·□, a pencil hardness of H or more but less than 6H, and 30 or less scratches in a steel wool test under a load of 500 g/cm², is also provided as the outermost layer on the light incident side. The film mirror has excellent antifouling properties and excellent scratch resistance, and is capable of maintaining good specular reflectance of sunlight for a long period of time. Also disclosed are: a method for producing the film mirror; and a reflection device for solar photovoltaic power generation using the film mirror.
