ABSTRACT:
A high-voltage variable resistor capable of significantly reducing a circuit board as compared with a prior art. Terminal fitments each are arranged so as to function as a connector for forming electrical connection between a slide element slid on each of variable resistance patterns and a terminal acting as an output section. A contact point between a contact on a contact support of the terminal fitment and a plate-like member of the slide element is positioned apart from a surface of the circuit board. The terminal fitment includes a positioner, which is positioned outside the pattern in a radial direction thereof, so that the positioner intersects the pattern while being spaced therefrom.
