PURPOSE:To form efficiently and surely a light reflecting layer on the uneven surface of a body having an uneven shape by coating the uneven surface with a heat-shrinkable light reflecting film having a thin metallic film on the side in a contact state. CONSTITUTION:A heat-shrinkable light reflecting film 1 is partially adhered to the uneven surface 3 of a body 2 of plastics, glass, metal or the like having an uneven surface shape with an adhesive, or the film 1 is wound around the surface 3, and both ends of the film 1 are adhered to each other. The whole body 2 is heated under prescribed conditions to shrink the film 1, so the surface 3 is coated with the film 1 in a contact state to form a light reflecting layer 1'. A thin metallic film of Al or the like is formed on the surface of a heat-shrinkable plastic film of polyethylene or the like by vapor deposition or plating, and the resulting film is used as the film 1. |
