PROBLEM TO BE SOLVED: To provide a method of manufacturing a flexible printed wiring board which prevents folds or wrinkles in production processes. SOLUTION: The method of manufacturing a flexible printed wiring board comprises laminating a work sheet (A), having the layout a plurality of circuit patterns 2, an adhesive film (B) with adhesives applied to one surface having an outline equal or less than the work sheet (A) and an insert film (C) having no adhesive and an outline less than the film (B), such that the film (C) is inserted between the sheet (A) and the film (B), heating and pressing them to form a unified laminated, and cutting it by each plurality of circuit patterns 2.
