摘要: The present invention relates to the resistors used for detecting current in a current-carrying circuit as a voltage, and aims to provides a resistor which assures highly accurate measurement of resistance even if the measuring point is not precisely placed. To obtain the above purpose, the resistor of the present invention comprises a sheet metal resistor element (11) and separate metal terminals (12),(13) electrically connected to both ends of the sheet resistor element(11). These terminals (12),(13) are made of metal having the same or greater electrical conductivity than that of the resistor element (11). With the above configuration, resistance of the terminals can be made smaller than that of the resistor element. This enables to reduce the proportion of resistance of the terminals in the entire resistor, allowing to ignore its effect on fluctuation of resistance due to deviation in measuring points of a resistance measuring terminal.
