Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a laminated sheet which has sunlight transmittance of a specified value or above and is excellent in stain resistance, designability, flexibility, and others by forming a fluororesin film from a fluororesin composition in which metal oxide fine particles are dispersed. SOLUTION: A flexible vinylidene fluoride(VDF) copolymer is used as a fluororesin, and a fabric of synthetic fiber spun yarns or filaments is used as a synthetic fiber fabric. Moreover, an organic ultraviolet absorber of an cyanoacrylate and others is added into a soft fluororesin film together with metal oxide fine particles. One or more fluororesin films and one or more synthetic fiber fabrics are laminated alternately. Although the thickness of the laminated sheet, which depends on its use conditions, is usually 200 μm-5 mm to have visible light the transmittance of which is at least 20%.
