PROBLEM TO BE SOLVED: To provide a back sheet for a solar cell module which has both adhesiveness and peelability.SOLUTION: The present invention relates to a laminated film which includes a support, a first adhesive layer laminated on at least one surface of the support, and a second adhesive layer laminated on the side opposite to the support via the first adhesive layer. Each of the first adhesive layer and the second adhesive layer contains a binder and a crosslinking agent. The total of average thicknesses of the first adhesive layer and the second adhesive layer is 0.05-3 μm. The ratio of the average thickness of the first adhesive layer to the total of the average thicknesses of the first adhesive layer and the second adhesive layer is 0.1-20%. The first adhesive layer and the second adhesive layer are colorless and transparent. |
