<p>PROBLEM TO BE SOLVED: To prevent water, oxygen, etc., from entering, to minimize deterioration of performance over a long period and realize high durability and protection ability by forming a laminated wherein a polyester resin layer with weather resistance and a cyclic polyolefin resin layer are laminated. SOLUTION: A protection sheet A1 for a solar battery module consists of a laminate 3a, wherein a weather-proof polyester resin layer 1 and a cyclic polyolefin resin layer 2 are laminated through an adhesive layer 4, etc. The laminate 3a is manufactured by laminating a polyester resin film or sheet constituting the weather-proof polyester resin layer 1 and a cyclic polyolefin resin film or sheet constituting the cyclic polyolefin resin layer 2 through a lamination adhesive layer, etc.</p> |
