Printed circuit board for preventing electrostatic discharge

The invention provides a printed circuit board for preventing electrostatic discharge. The printed circuit board comprises a board body, a conductor, a first protection element, a second protection element, a ground layer and a power supply layer. The board body is provided with a first surface, a second surface and a through hole. The conductor is arranged in the through hole. The first protection element is arranged on the first surface. The second protection element is arranged on the second surface, and the first and second protection elements are electrically connected by the conductor. The ground layer is positioned in the board body and between the first and second surfaces. The power supply layer is positioned in the board body and between the ground layer and the second surface. The ground layer, the power supply layer and the through hole are separated from one another.
