Method of manufacturing optoelectronic flexible printed circuit board

PROBLEM TO BE SOLVED: To provide a method of manufacturing a photoelectric flexible wiring board, a method by which warping is reduced of the photoelectric flexible wiring board during the manufacturing, by which mixing of contaminations on an optical waveguide forming face during the manufacturing is reduced, irregularities on the surface of the flexible wiring board caused by contaminations are reduced, and by which bending resistance, sliding resistance, and quality improvement of optical transmission loss can be achieved. SOLUTION: The flexible wiring board includes a protective layer for protecting the flexible wiring board surface on the optical waveguide forming face of the flexible wiring board. The method of manufacturing the photoelectric flexible wiring board includes a stage A for joining a support to the face opposite from the face having the protective layer and a stage B for removing the protective layer in this order.
