ABSTRACT:
A variable resistor for use in electrical and electronic equipment which includes a base plate, a lower stator terminal housed in a circular recess formed in one surface of the base plate, a rotor member having an electrically conductive film layer at its one surface and an electrically resistant film layer at its other surface and rotatably mounted on the lower stator terminal with the conductive film layer contacting the lower stator terminal, and an upper stator terminal fixed to the base plate so as to slidingly contact the resistant film layer under pressure.
