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 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 is configured to include a plate-shaped base material sheet, 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 provided on at least one of both surfaces of the base material sheet, which does not face the concave curved surface when mounted to the concave curved surface.
