Abstract:
A current measurement device comprising: a shunt resistor; a pair of first and second voltage signal lines connected to the shunt resistor; and a current measurement circuit for measuring a current using a signal by the pair of first and second voltage signal lines. The pair of first and second voltage signal lines are connected to an amplifier circuit with which the current measurement circuit is provided to amplify a voltage signal. A third signal line which is a signal line different from the pair of first and second voltage signal lines and drawn from the shunt resistor is connected to a common line of the current measurement circuit.
