Provided is a solar cell backsheet that retains excellent gas barrier properties and is excellent in weather resistance and light shielding properties. A solar cell backsheet having a light-shielding colored layer and a weather-resistant polyester-based resin layer, and having a gas-barrier layer including a weather-resistant coat layer and an inorganic thin film layer between these layers, The weather-resistant coating layer comprises (a) a crosslinked product of polycaprolactone polyol and / or polycarbonate polyol, (b) a crosslinked product of modified polyvinyl alcohol, and (c) an ultraviolet-stable group, an ultraviolet-absorbing group, and a cycloalkyl group. A solar cell backsheet comprising at least one acrylic copolymer having at least one group selected from the group consisting of: |
