A variable resistor in which the contact portion of a contactor can be brought into contact with a resistor with a pressure within a proper range over a long period by using a contactor containing carbon fibers. The held portion (7b) of the contactor (9) is held by means of a holder (17) such that the tip portion of the contactor (9) containing carbon fibers is brought into contact with the surface of the resistor (5).
