PURPOSE:To prevent a metallic deposited layer from being flawed and to prevent the decline of reflectivity and diffuse reflectivity of the metal, by sticking a roughened-surface processed plastic film, on which the mtal is deposited, to a screen base body. CONSTITUTION:Firstly, the surface of a plastic film 1 is processed to have a finely uneven surface. It is especially recommendable to use a polyester film or oriented polypropylene film for the plastic film 1. Then a metallic deposited film 2 is formed on the uneven surface of the plastic film 1 by uniformly depositing a metal and aluminum, silver, etc., is used as the metal. After the metallic deposited layer 2, a transparent resin layer 3 is formed on the layer 2 and it is especially recommendable to use polymethylmethacrylate as the transparent resin. Heat-sensitive adhesive films 4 are piled up on the surface of the plastic film 1, where the metal is not deposited, and a screen base body 5 is stuck to the four-layer laminated body.
