摘要： A voltage sensing device with which high-precision voltage sensing is possible without acquiring a unique correction constant for each device. A pair of voltage input nodes NCk and NCk-1 are selected from n+1 voltage input nodes NC0-NCn in switch part 10, and the selected voltage input nodes NCk and NCk-1 are connected to inspection input nodes NA and NB. Here, voltage input nodes NCk and NCk-1 and inspection input nodes NA and NB are connected in two types of patterns of different polarity (forward connection, reverse connection) under the control of control part 50, and digital data S30 for the two sensed voltage signals S20 generated in the two types of connection patterns is input to sensed data processing part 40. With sensed data processing part 40, sensed voltage data S40 that represents the potential difference between voltage input nodes NCk and NCk-1 is generated according to the difference in the two sensed voltage signals S20.
