Claim:
1. An opto-electric hybrid board comprising: an elongated insulation layer; an opto-electric module portion defined on at least one end portion of the insulation layer; an interconnection portion defined on a portion of the insulation layer extending from the opto-electric module portion; and a metal reinforcement layer provided on a back surface of the insulation layer as extending over the opto-electric module portion into a portion of the interconnection portion; wherein a first electric wiring of an electrically conductive pattern and an optical element are provided on a front side of the opto-electric module portion, wherein an elongated optical waveguide is provided on a back side of the interconnection portion and optically coupled with the optical element provided on the opto-electric module portion, wherein a portion of the metal reinforcement layer present in the interconnection portion has a smaller width than a greater width portion of the metal reinforcement layer present in the opto-electric module portion, and a boundary between the smaller width portion and the greater width portion of the metal reinforcement layer is rounded so as to include a rounded proximal corner, and wherein the metal reinforcement layer present in a portion corresponding to the rounded proximal corner has a width greater than a maximum width of the interconnection portion and has a width smaller than the greater width portion of the metal reinforcement layer.
