A manufacturing method for a printed circuit board is disclosed. The method includes: forming a first circuit pattern on a metal layer of a conductive carrier, which has the metal layer stacked on one side, pressing the conductive carrier and a first insulation layer together with the first circuit pattern facing the first insulation layer, forming a via by selectively removing the conductive carrier, and removing the metal layer. Using this method, a high-density thin package can be manufactured with increased reliability, and the productivity of the manufacturing process can also be improved.
