Abstract
An opto-electric hybrid board according to the present invention includes a substrate including an insulation layer and a metal reinforcement layer. An electric circuit part is provided on the front surface of the substrate, and an optical waveguide part is provided on the back surface thereof. The metal reinforcement layer includes an optical coupling through hole and an alignment through hole. The electric circuit part includes an electrical interconnect line, an optical element, a first alignment mark for positioning of a mirror part, and a second alignment mark for positioning of the optical element. The mirror part of the optical waveguide part is positioned with respect to the first alignment mark visually recognized through the alignment through hole, and the optical element of the electric circuit part is positioned with respect to the second alignment mark.
