Provided are a multilayer sheet superior in weather resistance, heat resistance, and moisture proofness and also favorable in interlayer adhesiveness, and a back sheet for solar cells and a solar cell module prepared by using the same. The multilayer sheet 10 is prepared by laminating a polyolefin-based resin layer 1 having a melt flow rate, as determined by the method A specified in JIS K7210, of 0.5 to 25 g/10 minutes at 230°C under a load of 2.16 kg and a polyvinylidene fluoride-based resin layer 2 having a melt flow rate, as determined by the method A specified in JIS K7210, of 0.5 to 25 g/10 minutes at 230°C under a load of 2.16 kg, via an adhesion resin layer 3 of a conjugated diene-based polymer, a conjugated diene-based copolymer, or the hydride thereof having a melt flow rate, as determined by the method A specified in JIS K7210, of 0.1 to 50 g/10 minutes at 230°C under a load of 2.16 kg. Aback sheet prepared by using the multilayer sheet 10 is layered on a sealing material of a solar cell, to give a solar cell module. |
