An opto-electric hybrid board is provided which includes a lens formed in an optical path between an optical element and a core with stable positional accuracy without the decrease in productivity. The opto-electric hybrid board includes: an electric circuit board (E) including an insulative layer (1) having front and back surfaces, and electrical interconnect lines (2) formed on the front surface of the insulative layer (1) ; an optical element (including a light-emitting element (11) and a light-receiving element (12)) mounted on a surface of the electric circuit board (E) with the electrical interconnect lines (2) formed thereon; and an optical waveguide (W) including a core (7) and formed on the back surface of the insulative layer (1) of the electric circuit board (E). The core (7) includes at its end portion a reflecting surface (7a) capable of reflecting a light beam (L) to propagate the light beam (L) between the core (7) and the optical element. The insulative layer (1) is made of a light-transmissive material. A portion of the insulative layer (1) corresponding to an optical path between the reflecting surface (7a) of the core (7) and the optical element is in the form of a lens portion (1a) . |
