Patent ID: 8606056

Claim:
An opto-electric hybrid board, comprising: an optical waveguide unit; and an electric circuit unit having an optical element mounted thereon, the electric circuit unit being coupled to the optical waveguide unit, wherein the optical waveguide unit comprises: an undercladding layer; a core for an optical path, the core being formed on a surface of the undercladding layer; an overcladding layer which covers the core; and a notch portion or a through hole for locating the electric circuit unit, the notch portion or the through hole being formed in a portion of at least one of the undercladding layer and the overcladding layer; wherein the electric circuit unit comprises: an electric circuit board; the optical element mounted at a predetermined portion on the electric circuit board; and a bent portion formed by bending a part of the electric circuit board so as to stand upright for fitting into the notch portion or the through hole of the optical waveguide unit; wherein the notch portion or the through hole in the optical waveguide unit is located and formed at a predetermined location with respect to one end surface of the core; wherein the bent portion of the electric circuit unit is located and formed at a predetermined location with respect to the optical element; and wherein the optical waveguide unit and the electric circuit unit are coupled to each other in a state in which the bent portion of the electric circuit unit fits into the notch portion or the through hole in the optical waveguide unit.
