Effects of the Invention As described above, the small variable resistor of the present invention has (1) an insulating substrate on which a resistor film is formed on one main surface;
An insulating material disposed on one main surface of the substrate or on the resistor film, except at least near the sliding portion of the contact of the slider on the resistor film, and a contact formed on the one surface side are a slider that is in sliding contact with the resistor film and is disposed so that at least a portion other than the contact on the one side of the slider is in sliding contact with the insulating material; (2) an insulating substrate with a resistor film formed on one main surface;
An insulating material is attached to the one surface side except for contacts formed on the one surface side, and the insulating material is arranged to be in sliding contact with at least the resistor film or the substrate, and the contacts are in sliding contact with the resistor film. By providing a conductive plate that is fixed to the substrate so as to contact the other surface of the slider and sandwich the slider between the slider and the substrate. To obtain a small, thin variable resistor that has a dust-proof structure, allows a thin slider to approach a resistor film across an insulating material, and eliminates the need to provide a space for insulation, etc. I can do it.
