Abstract
An opto-electric hybrid board includes opto-electric module portions respectively defined on opposite end portions of an elongated insulation layer, and an interconnection portion defined on a portion of the insulation layer between the opto-electric module portions and including an optical waveguide. A metal reinforcement layer extends over the opto-electric module portions into the interconnection portion. A portion of the metal reinforcement layer present in the interconnection portion has a smaller width than portions of the metal reinforcement layer present in the opto-electric module portions, and has a discontinuity extending widthwise across the metal reinforcement layer. This arrangement makes it possible to protect the optical waveguide from the bending and the twisting of the interconnection portion, while ensuring the flexibility of the interconnection portion including the optical waveguide.
