Abstract
A manufacturing method of shunt resistor according to the present invention includes a step of calculating a difference between an initial resistance value and a desired resistance value as a resistance value to be adjusted, a step of providing a plurality of recess forming members capable of forming recesses each having a characteristic size in the surface of a resistive alloy plate, a recess determining step of determining the size and the number of the recesses necessary to be formed at the surface of the resistive alloy plate, and a recess forming step of forming the recesses according to the size and the number determined in the recess determining step by using the corresponding recess forming members.
