PROBLEM TO BE SOLVED: To provide a solar cell module having high adhesion strength without causing weatherability degradation, in a back protective sheet of a thin-film solar cell.SOLUTION: In this solar cell module including solar cell elements sequentially laminated on a substrate, a sealing resin covering the entire surfaces of the solar cell elements, and a back protective sheet, the back protective sheet includes a primer layer comprising a fluorine-based copolymer, an acrylic copolymer or a polyurethane-based polymer, a polymerizing monomer having one or more ethylenic unsaturated groups and/or oligomer, and/or a compound containing one or more ethylenic unsaturated groups and two or more isocyanate groups in each molecule; and adhesion strength between the sealing resin and the back protective sheet is larger than 15 N/cm, and larger than 10 N/cm even after a weatherability test. |
