Disclosed herein is a printed circuit board, including: a substrate including a first circuit layer formed on one side thereof and a second circuit layer formed on the other side thereof; and a strike-type through body externally inserted in the substrate and electrically connecting the first circuit layer and the second circuit layer. The printed circuit board is advantageous in that, since a strike-type through body is externally inserted in a substrate, conventional complicated processes, such as hole forming, deburring, desmearing, electroless copper plating and electrolytic copper plating, can be omitted, thus simplifying a process of manufacturing a printed circuit board and reducing the manufacturing cost thereof.
