A multilayer wiring board assembly, a multilayer wiring board assembly component and a method of manufacture thereof are described in which it is possible to easily laminate together flexible FPCs having highly packing densities by via-on-via and chip-on-via. The multilayer wiring board assembly is laminated by laminating together a plurality of multilayer wiring board assembly components, each of which is made by preparing a copper plated resin film 10 made of a flexible resin film 1 which is provided with a copper foil 2 bonded to one surface thereof and an adhesive layer 3 bonded to the other surface, opening a through hole 7 in the copper plated resin film 10 through the resin film 1 and the adhesive layer 3, filling the through hole by screen printing from the copper foil 2 with a conductive paste to form a conductive paste filler 8 having a projection 8b as projected from the adhesive layer 3.
