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.
Claims7
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.
