It is an object of the present invention to provide a mounting sheet which can be easily mounted to a visor shield in a helmet, a lens in goggles, or the like and is less likely to come off. A mounting sheet 10 is a mounting sheet which is mounted to a concave curved surface, which is an inner wall surface of a visor shield or a goggle lens, in a state where the mounting sheet is deflected along the curved surface. The mounting sheet 10 is configured to include a plate-shaped base material sheet 100, which is formed of polycarbonate having a thickness of 0.1 mm or more and has a curvature smaller than that of a mounting surface when not mounted to the mounting surface, and an anti-fog layer 105 provided on at least one of both surfaces of the base material sheet 100, which does not face the concave curved surface when mounted to the concave curved surface.
