摘要： 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.

摘要： An opto-electric hybrid board includes an electric circuit board in which electric wiring is formed on a front surface of an insulating layer, and an optical waveguide formed on the rear side of the electric circuit board. The optical waveguide and the electric circuit board are arranged so that left and right edges of the electric circuit board along a longitudinal direction of the optical waveguide overlap with left and right edges of the optical waveguide when viewed from above, or so that the left and right edges of the electric circuit board are on the inside of where the left and right edges of the optical waveguide are located. The opto-electric hybrid board is easy to handle owing to the reduced chance of the electric circuit board being damaged. The opto-electric hybrid board also does not cause misalignment of a core when used as a connector.

摘要： There is provided an optical sensor in which a reduction in size of a light-receiving part is achieved. This optical sensor is installed in a device, and includes a light-receiving element 4 for receiving light coming from outside toward the device. The optical sensor detects the state of the received light. A linear optical waveguide 2 is connected to the light-receiving element 4 so as to be capable of light propagation. The optical waveguide 2 has a front end portion serving as a light entrance portion on which light coming from the outside of the device is incident.
