Patent ID: 8644660

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; and a core for an optical path and a socket portion for locating the electric circuit unit, the core and the socket portion being formed on a surface of the undercladding layer, the socket portion being formed of the same material as a forming material for the core; 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 socket portion; wherein the socket portion of the optical waveguide unit is located at a predetermined location with reference to a location at which the core is formed with respect to one end surface of the core; wherein the socket portion is capable of nipping; 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 socket portion of the optical waveguide unit.
