    • Disclosed is a manufacturing method of a printed circuit board. The method in accordance with an embodiment of the present invention includes: providing a laminated substrate having an insulator as well as a first metal layer and a second metal layer, which are sequentially laminated on one side of the insulator; processing a via hole in the laminated substrate; forming a seed layer on an inner wall of the via hole and on a surface of the second metal layer; plating an inside of the via hole and the surface of the second metal layer with a conductive material that is different from a material of the second metal layer; etching the seed layer and the conductive material, formed on the second metal layer; etching the second metal layer; and forming a first circuit pattern by selectively etching the first metal layer.
