Abstract
To provide voltage detection device capable of reducing variations and errors in detection voltage caused by influence of configuration of pattern wiring and temperature when detecting voltages applied to a plurality of resistance elements connected in parallel. Voltage detection device includes resistance unit including a plurality of resistance elements connected in parallel, differential amplifier circuit, first connection portion having two wiring portions connecting positions different from each other in one end portion of resistance unit and input terminal of differential amplifier circuit, and second connection portion having two wiring portion connecting positions different from each other in other end portion of resistance unit and input terminal of differential amplifier circuit. Voltage detection device configures to detect voltage applied to resistance unit based on voltage of output terminal of differential amplifier circuit.
