PROBLEM TO BE SOLVED: To provide a power supply device for an impulse voltage generator that can prevent the occurrence of a failure of the impulse voltage generator by preventing the occurrence of insulation breakage at a power supply transformer in the power supply device, even if a naked wire of an electric fence connected to an output terminal of the impulse voltage generator is broken and the naked wire is contacted to the ground and earthed, and even if an earth cable connected to an earth terminal of the impulse voltage generator is broken and the earth terminal is brought into a state of being floated from the earth, and furthermore can prevent the earth terminal of the impulse generator from being exposed to an AC voltage. SOLUTION: In the power supply device 100 of the impulse voltage generator of the electric fence that generates a DC voltage by reducing and rectifying the AC voltage of an AC power supply in order to actuating the impulse voltage generator 5 that applies impulse voltages to the naked wires 3a, 3b of the electric fence, surge absorbers Z1, Z2 of which the varistor voltages are smaller than a withstand voltage value of the power supply transformer T between the primary winding and the secondary winding of the power supply transformer T that reduces the AC voltage of the AC power supply.
