摘要：
A resistor circuit which includes a pair of linear conductive films and a resistive film. The resistive film is formed on an area between the conductive films and electrically connected to the conductive films. A pair of terminals are electrically connected to portions of the conductive films respectively. A current source is electrically connected between the terminals to flow an electric current between the terminals. A pair of voltage output terminals are electrically connected to portions of the conductive films respectively. At least one of the voltage output terminals is disposed at a position other than a position in which the terminals are formed. An output voltage output from the voltage output terminals is exactly proportional to a current flowing between them without an influence of change of an ambient temperature.
