Abstract
A method for producing a vinylidene fluoride resin film having excellent transparency, weather resistance, chemical resistance, break resistance and formability is provided. The film is shaped by sandwiching a vinylidene fluoride resin in a molten state between rollers or metal belts so as to let them cool down, thus realizing polyvinylidene fluoride with a fine average spherocrystal diameter. Thus, the vinylidene fluoride resin film having the above-stated properties can be obtained.
