1. A shunt resistor for use in current detection, comprising:
a base structure including a resistance element and a pair of electrodes coupled to both ends of the resistance element;
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,
wherein the bridge structure has a higher resistance than a resistance of the base structure at the connections, and
wherein the bridge structure includes voltage detecting portions arranged at both end-portion sides of the bridge structure.
