  • Resistance substrate and variable resistor
    Patent number: 7049927
    Abstract: A resistance substrate includes a substrate member, two conductive elements provided on the substrate member, and a resistor element provided on the substrate member, the resistor element electrically connecting the conductive elements to each other. Each of the conductive elements includes an exposed portion of a metal terminal and an electrode film, the exposed portion of the metal terminal being exposed on a surface of the substrate member and the electrode film being electrically connected to the exposed portion and extending along a direction in which the resistor element extends. Each of the conductive elements is covered by an insulator film such that an exposed portion of the electrode film is left uncovered. The resistor element is electrically connected to the exposed portions of the electrode films at both ends thereof.
