Abstract
The present invention relates to a resistor including a Ni-based alloy that consists of 15.0 mass %≤Cr≤25.0 mass %, 1.0 mass %≤Al≤4.0 mass %, 1.0 mass %≤Cu≤3.0 mass %, 0 mass %≤Si≤1.5 mass %, and 0 mass %≤Mn≤1.5 mass %, with the balance being Ni and inevitable impurities, in which the resistor has a Vickers hardness at 20° C. of 160 Hv or more and 230 Hv or less, a volume resistivity at 20° C. of 125 μΩ·cm or more and 150 μΩ·cm or less, and a temperature coefficient of resistance at 20° C. to 155° C. of −50 ppm/° C. or more and 10 ppm/° C. or less, and relates to a manufacturing method thereof.
