(54) Reflector substrate for illumination device and reflector for illumination device


(57) A reflector substrate 1 for an illumination device comprises an aromatic polyimide film or aromatic polyamide film molded article.
In addition, a reflector 8 for an illumination device is comprised of a reflecting layer 10 generated by vapor depositing a reflecting material on a reflector substrate comprising an aromatic polyimide film or an aromatic polyamide film molded article. The reflector substrate of the invention is light in weight and excellent in surface smoothness, safety, moldability, heat resistance, and handling characteristics. The reflector substrate requires no pre-treatment when the reflector layer is generated and it is suitable for mass production.
