ABSTRACT:
A high-voltage variable resistor includes an insulating-resin front case, and an insulating-resin rear case fitted to the front case. The front case further includes a circuit board having a circuit pattern including a resistive element, and a slider that is slidable on the resistive element. The rear case includes a capacitor housing for accommodating a capacitor, and a terminal guide for accommodating an external connection terminal. The capacitor housing and the terminal guides are integrally molded with the rear case.
