Abstract
A light-conductive circuit unit comprises a substrate (1) made of an optical material, the substrate (1) having a light inlet surface (1a) for letting in a beam of light from a light source (2a to 2c), a light outlet surface (1b) for letting out a beam of light to a light-receiving element (3a to 3g), and a light-conductive path (4a to 4h) constituted with a part of the substrate to conduct rays of light from the light inlet surface (1a) to the light outlet surface (1b), and a combination of light course turning parts (5a to 5g) and optical switching mechanisms (6a to 6e) both substantially integrated with the substrate (1).
