A shunt resistance type current sensor includes a bus bar that is a path of an electric current to be measured, a circuit board that is installed over the bus bar, a pair of connecting members that electrically connect the circuit board with the bus bar, a voltage detection unit that is provided on the circuit board and detects a voltage value applied to the circuit board through the pair of connecting members so as to calculate a level of the electric current flowing through the bus bar, and a temperature sensor that is provided on the circuit board to face the bus bar and detects a temperature of the bus bar to allow the voltage detection unit to perform a correction regarding the calculation of the level of the electric current. |
