Abstract
An optical wiring board by which an optical waveguide can be easily aligned with a light emitting element and a light detecting element. The optical wiring board (1) is provided with a substrate (10). On the substrate (10), a plurality of recessed parts (12) are formed, and the optical waveguide (13) is formed between the recessed parts (12). In the recessed part (12), a light receiving/emitting member (30), which is mounted on an inserting part (22) on a base member (20), is arranged. In the inserting member (22), reflecting planes (26, 27) are formed on inclined planes, and an optical path of the optical waveguide (13) matches with that of a light detecting part (34) and a light emitting part (37) in the light receiving/emitting member (30) via the reflecting planes (26, 27).
