<p>A board (10) of an optical divider (1) is provided with a light incidence part (21) which light enters, light dividing parts (22A-22G) which divide the light entered the light incidence part at a prescribed rate, light projecting parts (23A-23H) which guide the light divided by the light dividing part to prescribed positions, and dummy patterns (24A-24H), which are arranged on the board independently from board areas whereupon the light incidence part, the light dividing part and the light projecting part are arranged, by using the same material as that of the light incidence part, the light dividing part and the light projecting part, so as to have more than 70% occupation ratio, which is a ratio of an area excluding the board areas whereupon the light incidence part, the light dividing part and the light projecting part are arranged.</p> |
