ABSTRACT:
A chip-type variable resistor is provided which includes an insulating substrate formed with a resistor strip which is arcuate at least partially and has both ends electrically connected to respective extremity electrode terminals, an intermediate terminal member mounted to the substrate, and a contact member electrically connected to the intermediate terminal member and rotatably mounted to the substrate in slidable contact with the resistor strip. The resistor strip includes at least one portion having a lower area resistivity (defined as a resistance per unit surface area) and at least another portion having a higher area resistivity.
