ABSTRACT:
There is provided a variable resistor having a small number of parts and having an excellent heat releasing property. A rotor is rotatably contained in a concave portion of a case. The rotor has a resistive element provided on the bottom thereof and electrodes connected to both ends of the resistive element. Arms of sliders are provided on the bottom of the concave portion of the case in a sliding relationship with the respective electrodes and resistive element. A metal cover is disposed on the upper surface of the case in contact with the rotor.
