Abstract:
1. An opto-electric hybrid board, comprising: an optical waveguide unit; an electric circuit unit having an optical element mounted thereon; and a coupling pin for coupling the optical waveguide unit and the electric circuit unit to each other, wherein the optical waveguide unit comprises: wherein the electric circuit unit comprises: wherein one end edge of the optical waveguide is formed as an inclined light reflecting surface which is inclined 45° with respect to an axial direction of the core so that light reflected by the light reflecting surface can be transmitted between the core and the optical element; wherein the fitting hole in the optical waveguide unit is located and formed at a predetermined location with respect to an end surface of the core; wherein the fitting through hole in the electric circuit unit is located and formed at a predetermined location with respect to the optical element; wherein the shape and size of a cross-section of the coupling pin, which is at a right angle to an axis of the coupling pin, are identical to the shapes and sizes of cross-sections of the fitting through hole and the fitting hole, which are at a right angle to the axes of the fitting through hole and the fitting hole; wherein the optical waveguide unit and the electric circuit unit are coupled to each other in a state in which the coupling pin fits through the fitting through hole in the electric circuit unit and fits into the fitting hole in the optical waveguide unit, wherein the coupling pin and the electric circuit board are in direct contact with each other, wherein the electric circuit board is disposed directly on the overcladding layer of the optical waveguide unit, and wherein the coupling pin and the overcladding layer are in direct contact with each other.
