PROBLEM TO BE SOLVED: To manufacture a flexible wiring board while a cost required for production facilities is suppressed. SOLUTION: An insulating substrate 2 is fixed to a fixing jig 1 so that the surface of copper foil 3 may be exposed, and while the insulating substrate 2 is still fixed to the fixing jig 1, the copper foil 3 is etched using resist patterns 4a, 4b and 4c as masks, thus forming wiring patterns 3a, 3b and 3c on the insulating substrate 2.
