Provided is a voltage sensor module monitoring a voltage of each of a plurality of battery cells, including: first and second terminals each receiving a voltage applied between both ends of the plurality of battery cells; third and fourth terminals each receiving a voltage applied between both ends of a battery cell to be monitored which is included in the plurality of battery cells; a first reference voltage generation circuit connected to each of the first and second terminals and generating a first reference voltage based on the voltage applied between the both ends of the plurality of battery cells; and a first comparator circuit comparing a first regulated voltage generated based on a voltage applied between the third and fourth terminals, with the first reference voltage. As a result, low voltage detection can be performed with accuracy even when an output of a battery cell decreases.
