Abstract
A photoelectric composite module has an optical device, a package and a flexible printed circuit that is set along both case parts of the package, and electric wiring for the optical device is formed thereon. The package has a first case part and a second case part that is connected with the first case part by a hinge and is set on a mounted board. The optical device is joined with a surface that faces the first case part in said flexible printed circuit. The flexible printed circuit has light extraction means for transmitting an optical signal that should be exchanged between the optical device and the optical waveguide. The package has short-circuiting means for making a short circuit between the electrical wiring of the flexible printed circuit and the electrical wiring of the mounted board.
