Abstract
An object of the invention is to provide a reflective sheet that uses silver which exhibits a high reflectance as a reflective layer and is excellent in light resistance and wet heat durability, as well as a lamp reflector that uses the sheet and does not generate a luminescent line. The reflective sheet constituted by sequentially arranging at least three layers, that is, an underlying layer, a metal layer made primarily of silver and a protective layer on a polymer film is laminated with a molded body by using an adhesive, allowing a polymer film side of the reflective sheet to be a surface to be adhered, to prepare a reflector. The resultant reflector is processed to prepare a lamp reflector.
