PROBLEM TO BE SOLVED: To obtain a film having excellent durability which prevents fog only by adhering the film to a window glass or the like by forming a ceramic transparent hydrophilic coating film which has no photocatalytic function and which consists of oxides of silicon, aluminum, zirconium or the like on the surface of a transparent synthetic resin film, and then forming a transparent adhesive layer to the back surface. SOLUTION: As for the synthetic resin film, a polyester or acryl resin is preferably used because it has good adhesiveness with an adhesive, and the thickness of the film is 7 to 100μm, preferably 12 to 30μm. The hydrophilic coating film consists of a transparent ceramic material having no photocatalytic function and consists of, for example, silicon dioxide, aluminum oxide and zirconium oxide. The hydrophilic coating film is preferably formed to 10 to 1000Åthickness, especially 50 to 100Å, by physical vapor deposition such as vacuum vapor deposition, sputtering, arc discharge and ion beam method. Especially, sputtering is preferably used. Then a transparent pressure-sensitive cohesive adhesive layer is formed on the back surface of the synthetic resin film.
