PROBLEM TO BE SOLVED: To provide a method for producing a fluororesin film, which can produce a fluororesin film having high optical transparency by a simple method.SOLUTION: A method for producing a fluororesin film can produce a film that has characteristics such as weather resistance, etc., originated from a fluororesin and high optical transparency in a wide wavelength range at a low cost by a simple operation in which a fluororesin in a molten state is quenched at a cooling rate of 50-1,000°C/s and then stretched into a film. The obtained film has a scattering peak originated from a &bgr; phase and the fluororesin film is provided with ferroelectricity such as piezoelectricity, etc., by a polling treatment. |
