A photoelectric module device comprising a multiple layer printed circuit board and at least one photoelectric module device is provided. The multiple layer printed circuit board has at least an upper circuit board substrate, a lower circuit board substrate, and a circuit. A plurality of photoelectric elements are installed on the multiple layer printed circuit board and is electrically connected to the circuit. The photoelectric elements are packaged above the multiple layer printed circuit board by injection molding a transparent resin thereon. The lower substrate has a plurality of through holes formed therein and the inner wall of the through holes is plated with metal, as an electric terminal. The upper circuit board substrate serves to seal the through holes and prevent resin from permeating therein during the injection molding process. When the circuit board is cut into separate photoelectric module devices, after packaging, the inner wall of the through holes are partially cut away and the remaining portion thereof becomes a terminal for electrically connecting to external devices.
