A shunt resistor includes a resistive body and a pair of electrodes each bonded to the resistive body. The resistive body has an obverse surface and a reverse surface that face in mutually opposite directions. The two electrodes are separate from each other in a first direction perpendicular to the thickness direction of the resistive body. The resistive body has two ends separate from each other in the first direction. The obverse surface of the resistive body includes a pair of intentionally curved portions that are located at the two ends of the resistive body.
