Abstract: An electronic apparatus includes a printed circuit board, a terminal and a surge voltage protection structure. The printed circuit board includes a first plated through hole, a second plated through hole and a ground terminal. The surge voltage protection structure includes the first plated through hole and the second plated through hole. The first plated through hole is electrically connected to the terminal. The second plated through hole is connected to the ground terminal. A gap is defined between the first plated through hole and the second plated through hole. The first plated through hole receives a surge voltage to generate an electric arc across the gap and transmit the electric arc through the gap to the second plated through hole, so that the second plated through hole receives the electric arc to transfer an energy of the electric arc to the ground terminal.
