Provided is a stacked-battery internal resistance measurement circuit that applies current to a stacked battery constituted by a plurality of stacked single cells, and that, on the basis of the applied current as well as the potential at a specific portion of the stacked battery to which the current has been applied, measures the internal resistance of the stacked battery. The stacked-battery internal resistance measurement circuit is provided with a source circuit that applies current to the stacked battery, and a sense circuit that measures the potential at a specific portion of the stacked battery to which the current has been applied. A shielding section is provided between the source circuit and the sense circuit in order to shield the sense circuit from magnetic flux from the source circuit. |
