(57) [Summary] [Purpose] A light reflector consisting of a repeating pattern such as an encoder that has excellent wear resistance, adhesiveness, and light reflectivity. [Structure] From the light incident side, a SiO layer 22, an Al layer 21, A SiO layer 20, a resin layer 18 having a repeating pattern of a mirror surface and a rough surface, and a base material layer 17 are laminated in this order, and an encoder and the like having excellent wear resistance, adhesive strength, and light reflectivity are repeatedly formed. A patterned light reflector is obtained. |
