PROBLEM TO BE SOLVED: To provide a method of manufacturing a printed circuit board (PCB) or a flexible printed circuit board (FPCB) by direct printing. SOLUTION: The method includes (1) a step of printing a pattern on a substrate by a paste composition containing conductive particles, polyamide acid as a binder and a solvent, (2) a step of baking the printed circuit board and imidizing polyamide acid, and (3) a step of electroplating the printed circuit board. The printed circuit board (PCB) or the flexible printed circuit board (FPCB) manufactured by the method is provided. A manufacturing process is simplified, time and a cost are economized, an addition method of direct printing is applied while minimizing waste and the printed circuit board (PCB) or the flexible printed circuit board (FPCB) can be manufactured.
