ABSTRACT:
A vinylidene fluoride-based resin film including polyvinylidene fluoride whose average spherocrystal diameter is less than 0.1 μm that is a detection limit or lower by observation using a transmission electron microscope is provided, the average spherocrystal diameter being obtained by shaping a vinylidene fluoride-based resin in a molten state by sandwiching the resin between rollers or metal belts so as to let it cool down. Thereby, a vinylidene fluoride-based resin film and a vinylidene fluoride-based resin multilayered film having excellent transparency, weather resistance, chemical resistance, break resistance and formability are provided.
