In order to provide a method for inexpensively and stably producing build-up multilayer printed circuit boards having a stacked via structure allowing high-density mounting, a build-up multilayer printed circuit board is provided with: a flexible insulating base material (1); inner-layer circuit patterns (11A, 11B) formed on both sides of the insulating base material (1); and a double-sided core substrate (16). Said double-sided core substrate (16) comprises: an embedded via (6) that passes through the insulating base material (1) and is electrically connected to the inner circuit patterns (11A and 11B); and a cover plating layer (9) that covers the receiving land sections of the inner layer circuit patterns (11A, 11B) exposed by the embedded via (6), and the surface layer of which comprises gold, silver or nickel. The build-up multilayer printed circuit board is further provided with a build-up layer laminated on the double-sided core substrate (16). The build-up layer comprises an outer layer circuit pattern (23) on the surface layer, and a blind via (22A) that is electrically connected to the outer layer circuit pattern (23) and the inner-layer circuit pattern (11A). The blind via (22A) constitutes the embedded via (6) and a stack via structure.
