To improve a damp-proof characteristic and suppress performance deterioration by providing a contamination preventing layer consisting of an applied film of a composed material containing photo-catalyst powder and/or an ultraviolet ray absorbing agent layer on one and/or both sides of a laminated body of a fluorine resin sheet and a vapor-deposited film of an inorganic oxide.
A resin film 3 of a vapor-deposited film 2 of an inorganic oxide is laminated on one surface of a fluorine resin sheet 1. Further, a contamination preventing layer 5 and/or an ultraviolet ray absorbing agent layer 6 are/is provided on either or both sides of a laminated body 4 of the resin film 3 having the vapor-deposited film 2 of the inorganic oxide, and the contamination preventing layer 5 forms the outermost surface. As the fluorine resin film or sheet, one or more fluorine resins are used, and the fluorine resin is formed alone into a film through an extrusion process, etc. As the vapor-deposited film 2 of the inorganic oxide, a thin film vapor-deposited with a metal oxide can be used. The laminated body 4 is laminated via a laminating adhesive layer or laminated via a fused extrusion resin layer with a fused extrusion adhesive resin.
