Abstract
Provided is a current detection resistor, such as a shunt resistor, wherein a. low specific resistance and a small thermal electromotive force with respect to copper are achieved, while maintaining a low TCR. A resistance alloy for use in a current detection shunt resistor includes 4.5 to 5.5 mass % of manganese, 0.05 to 0.30 mass % of silicon, 0.10 to 0.30 mass % of iron, and a balance being copper, and has a specific resistance of 15 to 25 μΩ·m.
