Resistor for detecting current

摘要

Provided is a resistor for detecting current, which includes a voltage terminal member capable of removing an influence of error voltage, formed by tiny amount of self inductance existing in the resistor. The voltage terminal member includes a resistance body (11); a pair of electrodes (12) fixed to each end of the resistance body; and a pair of voltage terminal members (3) for detecting voltage generated in the resistance body and that are connected to each electrode; wherein the voltage terminal member (3) includes a connecting portion (3b) for connecting to the electrode (12), an extending portion (3c1,3c2) extending from the connecting portion toward the other electrode side; and wherein each end of the extending portion reaches to same plane (X) perpendicular to current path between the electrodes.
