PROBLEM TO BE SOLVED: To provide a high-voltage variable resistor which is capable of regulating the other voltage in a shorter time, after the adjustment of one voltage, when a plurality of voltages, has been regulated. SOLUTION: A high-voltage variable resistor is provided with a first variable resistor R2 and a second variable resistor R9, which are formed on an insulating board 1 and a first voltage output F1 and a second voltage output F2 via which the divided voltages, that are obtained by dividing an input voltage applied to the variable resistors R2 and R9 through the intermediary of sliders S1 and S2 sliding on the resistors R2 and R9, are outputted to the outside, where the first voltage output F1 is connected to a halfway point of the second variable resistor 9.
