Abstract
A variable resistor suitable for use in the tone control of a stereo tape player or the like has two resistance bodies formed on an insulating substrate plate so as to oppose one another. Under one of the resistance bodies is formed a lead conductor, through an interposed insulating layer. The lead conductor is connected to one end of the associated resistance body and leads to the other end portion of this resistance body, so that the terminals of both resistance bodies can be located at the same side of the insulating substrate plate, thereby to diminish the size of the variable resistor.
