Provided is a combined variable resistor wherein two or more signals can be adjusted while being associated with one another, by a simple structure. A combined variable resistor (10) contains an affixed resistor portion (11) and a movable contact portion (20) supported so as to slide with respect to the resistor portion, and is constructed so that the resistor portion is comprised of a plurality of resistor elements (12, 13, 14) which are affixed so that the surfaces thereof are in parallel with one another; the plurality of resistor elements are respectively provided with a stationary terminal portion (12d), and have a plurality of conductor portions connected to the stationary terminal portion via a resistor, on the surfaces thereof; the movable contact portion corresponds to the plurality of resistor elements, and is provided with a plurality of contacts (23, 24, 25) supported so as to respectively slide along the surfaces of the corresponding resistor elements; the plurality of contacts are connected to one another, and are electrically connected to a single movable terminal portion (26); the movable contact portion is moved in parallel with the surfaces of the resistor elements, so that each resistance value between the movable terminal portion of the movable contact portion and each contact provided on the tip of each resistor element, can be adjusted.
