There is provided a printed circuit board, including: a core layer, a conductive via formed in a via hole of the core layer, an upper land formed on an upper surface of the conductive via, and a lower land formed on a lower surface of the conductive via, wherein a center of the upper land and a center of the lower land do not coincide with each other on a plane, so that the center of the upper land and the center of the lower land formed in the printed circuit board are arranged so as not to coincide with each other, thereby increasing durability of an insulating region against pressure in a wet process, and thus damage to the printed circuit board can be reduced. |
