Abstract
A shunt resistor capable of reducing an absolute value of a temperature coefficient of resistance is disclosed. The shunt resistor includes: a base structure including a resistance element and a pair of electrodes; a bridge structure configured to bridge the pair of electrodes and made of a conductor; and connections configured to couple the pair of electrodes to the bridge structure. The bridge structure has a higher resistance than a resistance of the base structure at the connections.
