PROBLEM TO BE SOLVED: To provide a variable resistor capable of decreasing a concentrating contact-resistance generated in a boundary between the surface of a resistor and a slider, and superior to a linearity characteristic. SOLUTION: An electrode pattern print formed on a thermoplastic susbtrate comprising a heat-pressed conductive coating film enhances a sulfuration resistance and a sliding resistance of the electrode pattern. This decreases the concentrating contact-resistance between the slider and the electrode pattern, and an output voltage of the slider is in proportion to the sliding distance, which improves the linearity characteristic (linearity).
