Abstract
A surge absorbing circuit capable of absorbing surge stably without affecting a signal on a signal line even in the case of a high frequency signal, and an electronic device using the surge absorbing circuit. The surge absorbing circuit includes at least one surge suppression circuit, the at least one surge suppression circuit including, with respect to the same signal line at least: a power supply; a diode connected between the signal line and the power supply; and a power supply line for connecting the diode and the power supply to each other. In each of the at least one surge suppression circuit, a direction of the diode and a voltage of the power supply with respect to the signal line are determined so that the diode is reversely biased.
