PROBLEM TO BE SOLVED: To obtain a PVDF-based coating film for a solar cell back protective sheet which is excellent in thickness precision, is easily made thin, and is small in post-shrinkage; and to provide the solar cell back protective sheet using the same, and a solar cell module.SOLUTION: The vinylidene fluoride-based resin film is formed of a resin composition containing a vinylidene fluoride-based resin and a copolymerized resin (MS resin) of a (meth)acrylic acid ester monomer (MMA monomer) and a styrene monomer (MS resin). In the mixing rate of the respective resin components, the resin composition preferably contains 95 to 50 pts.mass of the vinylidene fluoride-based resin and 5 to 50 pts.mass of the copolymerized resin (MS resin) of the (meth)acrylic acid ester monomer (MMA monomer) and styrene monomer (MS resin). Further, 5 to 30 pts.mass of titanium oxide may be contained based on 100 pts.mass of the resin components in total so as to impart a light-shielding property to the film. |
