Abstract
The manufacturing method of the flexible printed wiring board relating to an embodiment includes a step of preparing a metal foil clad laminateincluding an insulating substrateand metal foiland metal foilprovided on main surfaces of the substrate, a step of forming a circuit patternby patterning the metal foil, a step of forming a peelable printing plate layeron the substrateso as to embed the pattern, a step of forming blind holesandwhere the patternis exposed inside by partially removing the printing plate layer, a step of printing conductive paste with the printing plate layeras a printing mask, and filling the conductive pasteinside the blind holes, and a step of peeling off the printing plate layerfrom the metal foil clad laminate
