The present invention relates to a method for manufacturing a printed circuit board, more particularly to a method for manufacturing a printed circuit board, in which an oxidant capable of polymerizing conductive polymers is selectively marked on a board using imprinting, and the monomer of a conductive polymer is filled in the selected pattern and polymerized, to provide a conductive polymer wiring pattern. With the method for manufacturing a printed circuit board according to certain aspects of the invention as set forth above, a printed circuit board can be given finer wiring widths to allow a highly integrated, highly efficient printed circuit board. Thus, a printed circuit board (PCB) or a flexible printed circuit boards (FPCB) can be manufactured that is applicable to industrial, clerical, and domestic electric electronic products, by a new technique of forming conductive polymer wiring using imprinting.
