Patent ID: 8303875

Claim:
A method for producing a vinylidene fluoride resin film that includes a vinylidene fluoride resin layer as a surface layer and a methacrylic resin composition (C) layer as a base layer, the base layer being laminated on one side of the surface layer, the method comprising: shaping a vinylidene fluoride resin in a molten state as the surface layer and a methacrylic resin composition (C) as the base layer by sandwiching the vinylidene fluoride resin and the methacrylic resin composition (C) between rollers or metal belts at a temperature of 10° C. to 100° C. so as to cool down the vinylidene fluoride resin and the methacrylic resin composition (C), wherein an average spherocrystal diameter of polyvinylidene fluoride in the produced vinylidene fluoride resin film is less than 1.0 μm by observation using a transmission electron microscope.
