PROBLEM TO BE SOLVED: To provide a laminate sheet for a solar battery module, which is arranged by directly laminating a white backside protective sheet for a solar battery module and a seal-material sheet on each other, and which is superior in solar battery module's processability, and less in yellow discoloration under a high-temperature and high-humidity condition of a temperature 85°C and a humidity of 85%RH.SOLUTION: A laminate sheet for a solar battery module comprises: a white backside protective sheet for a solar battery module, which is arranged by laminating a polyolefin-based resin film and a plastic film on each other; and a seal-material sheet directly laminated thereon to be put on the polyolefin film. The content of a phenolic antioxidant included in the polyolefin-based resin film is 0.05 wt% or less, and the content of a phosphorus-phenolic antioxidant is in a range of 0.02-0.2 wt%.SELECTED DRAWING: Figure 1 |
