An opto-electric hybrid board according to the present invention includes a substrate 32 including an insulation layer 30 and a metal reinforcement layer 31. An electric circuit part 33 is provided on the front surface of the substrate 32, and an optical waveguide part 34 is provided on the back surface thereof. The metal reinforcement layer 31 includes an optical coupling through hole 31a and an alignment through hole 31b. The electric circuit part 33 includes an electrical interconnect line 35, an optical element 50, a first alignment mark 36 for positioning of a mirror part, and a second alignment mark 37 for positioning of the optical element. The mirror part 43 of the optical waveguide part 34 is positioned with respect to the first alignment mark 36 visually recognized through the alignment through hole 31b, and the optical element 50 of the electric circuit part 33 is positioned with respect to the second alignment mark 37. Such a configuration allows the optical element 50 and the optical waveguide of the optical waveguide part 34 to be aligned with each other with very high accuracy. |
