There is also a method of depositing aluminum directly on the reflector base material without applying an undercoat, but the adhesion between the base material and aluminum cannot be obtained. However, since the polymer film is formed on the reflector base material, the adhesion of aluminum at the time of aluminum vapor deposition is improved.
