A printed circuit board and a method of manufacturing the printed circuit board are disclosed. The method of manufacturing a printed circuit board, by forming at least one bump for interlayer conduction on a surface of a board and stacking an insulation layer on the surface of the board, can include the operations of forming at least one dam on the surface of the board that surrounds a region corresponding to the bump, forming the bump by printing conductive paste onto the region corresponding to the bump, and stacking the insulation layer onto the surface of the board. This method can be utilized to improve productivity and resolve the problem of spreading.
