Provided is a fluorine resin film having a heat ray-shielding function, through which film it is possible to see natural colors of a colorless translucency, without any adverse effect on the high translucency, strong mechanical properties, robust weather resistance, and other properties inherent to a fluorine resin. Also provided is a fluorine resin film which provides the mechanical properties, translucency, long-term weather resistance, and other properties of a fluorine resin film; which has excellent heat ray shielding; and through which natural colors can be seen with a colorless translucency. A fluoreresin film containing indium tin oxide having a mean particle size of 10-200 nm and a blue pigment having a mean particle size of 10-200 nm is characterized in that the indium tin oxide content A (wt%) and blue pigment content B (wt%) in the film simultaneously satisfy equations (1) and (2). 10/t ‰¤ A ‰¤ 60/t (1) 0.05A ‰¤ B ‰¤ 0.3A (2) In the equations, t represents the film thickness (µm). |
