Abstract
Provided is a vinylidene fluoride resin composition resistant to yellowing in the test for evaluation of durability of moist heat resistance, even when it is laminated directly on an ethylene vinyl acetate copolymer (EVA)-based sealing material, and a resin film, a back sheet for solar cells and a solar cell module comprising the same. A vinylidene fluoride resin composition at least comprising a vinylidene fluoride resin having a peak value ratio of head-to-tail bond to head-to-head bond (head-to-tail bond/head-to-head bond), as determined byH-NMR, of 11.5 or less and a mass-average molecular weight (Mw) of 1.30×10or more, and an antioxidant is processed into a vinylidene fluoride resin film having a thickness of 10 to 200 μm. The vinylidene fluoride resin film and an electric insulating resin film such as polyethylene terephthalate-based film are laminated, to give a back sheet for solar cells.
