Patent ID: 8055105

Claim:
An opto-electric hybrid module comprising: an optical waveguide portion; an electric circuit portion; and an optical element mounted on the electric circuit portion, said optical waveguide portion including an under cladding layer, a linear core for an optical path and formed on a surface of the under cladding layer, an over cladding layer for covering the core, the over cladding layer being formed by using a die-molding, and protrusions for the positioning of the electric circuit portion and formed on the over cladding layer by using the die-molding, the protrusions being made of the same material as the over cladding layer, said electric circuit portion including a substrate, an electric circuit including pads for the mounting of the optical element and formed on the substrate, and through holes for fitting engagement with the protrusions for the positioning of said electric circuit portion, said optical element being an accepted product as a result of an appropriate mounting inspection performed, with said optical element mounted on the pads for the mounting of said optical element, said through holes in said electric circuit portion being brought into fitting engagement with the protrusions in said optical waveguide portion for the positioning of said electric circuit portion, whereby the electric circuit portion with the optical element mounted thereon and the optical waveguide portion are integrated with each other into the opto-electric hybrid module.
