As explained above, in this invention, a release film is placed on the upper surface of a mold made of a material with a small coefficient of linear expansion and has a mirror-finished molding surface, a resin layer is formed on top of the mold release film, and a resin layer is formed on top of the mold release film. A semi-cured fiber-reinforced plastic board is placed on it, pressurized and heated to form a reflector base material, and after demolding, a thin metal film such as aluminum is deposited on the resin layer of the reflector base material to form a reflective surface. Due to the manufacturing method, the coefficient of linear expansion is small.
By using FRP plates, it is possible to manufacture reflective mirrors with little dimensional change due to temperature changes. Furthermore, after demolding, a resin layer with a mirror-like surface is attached to the FRP board, which has the effect of omitting the step of polishing the surface to give it a mirror-like finish. Alternatively, since a release film is used instead of a release agent, it can be easily removed from the mold, and unlike a release agent, it does not adhere to the resin layer, so removal processing can be omitted. This has the effect of improving adhesion.
