To provide a fluororesin film on which no bubble streaks are formed even when it contains a sufficient amount of titanium oxide, in which deterioration of the fluororesin is suppressed, and which has a low transmittance of ultraviolet light at a wavelength of at most 360 nm and has excellent weather resistance and heat resistance, a method of its use, a backsheet for a solar cell module, and a solar cell module. n A fluororesin film containing an ethylene/tetrafluoroethylene copolymer as the main component, to be used for an outermost layer of a backsheet of a solar cell module, which contains specific titanium oxide composite particles and has an arithmetic mean roughness Ra of the film surface to be in contact with the air of at most 3 μm, and a method of its use. Further, a backsheet 1 comprising a laminate having a fluororesin film 11 , and a solar cell module comprising the backsheet. |
