Abstract: A high-voltage variable resistor capable of significantly small-sizing a circuit board as compared with the prior art. A terminal fitment is provided so as to act as an electrical connector for establishing electrical connection between a slide element fixed on an operation shaft member and slid on a variable resistance pattern formed on a circuit board and an output portion thereof. The terminal fitment includes a contact holding portion which is provided at a distal end thereof with a contact portion. A contact point between the contact portion of the terminal fitment and a contact portion of the slide element is defined on a side of the operation shaft member while being spaced from a front surface of the circuit board. Such construction prevents the contact point from being defined at a central portion of the variable resistance pattern, resulting in a radius of curvature of the variable resistance pattern being reduced as compared with that in the prior art.
