Shunting resistor and current sensor

The invention provides a shunt resistor and a current sensor, two ends of a resistance element of the shunt resistor are respectively provided with a plurality of voltage sampling nodes which are distributed at intervals, the voltage sampling nodes at the two ends are in one-to-one correspondence to form a plurality of current sampling paths, and the voltage sampling nodes are arranged at intervals so as to be conveniently led out respectively. According to the shunt resistor and the current sensor provided by the invention, a plurality of current sampling paths are provided for detecting the current of the resistor element, so that the voltage of the plurality of current sampling paths can be averaged conveniently; therefore, the increment and the decrement of the detection voltage of each current sampling path can be counteracted to a certain extent, the deviation between an actual voltage detection value and an ideal voltage detection value is reduced, the deviation of a current detection value correspondi
