PROBLEM TO BE SOLVED: To provide an opto-electric hybrid board in which a recessed portion for identification having the shape of a cross and the like is recognizable by means of recognition device and the like when the recessed portion is formed in an alignment mark, and to provide a method of manufacturing the opto-electric hybrid board. SOLUTION: An opto-electric hybrid board includes an optical waveguide portion 2, an electric circuit board 1, and optical elements mounted on this electric circuit board 1. In the optical waveguide portion 2, a linear core 22 for an optical path and protruding alignment marks 24 for positioning of the optical elements and each having a surface formed with a recessed portion 24a for identification are formed on a surface of a translucent under-cladding layer 21. The core 22 is covered with an over-cladding layer 23. The alignment marks 24 are covered with a translucent resin film 25 so that the recessed portion 24a of each of the alignment marks 24 is formed as a hollow portion A filled with air.
