Claim:
1. A boosting device, comprising: a battery; a capacitor connected in parallel with the battery and configured to store a pre-boosting voltage; a boosting converter including a reactor connected to the capacitor and a switching element connected to the reactor, and configured to obtain a boosted voltage by switching the switching element; a boosted voltage sensor configured to detect the boosted voltage; a current sensor configured to detect a reactor current flowing through the reactor; a pre-boosting voltage sensor configured to detect the pre-boosting voltage; and a control unit configured to control the boosting converter by feedback control of the boosted voltage detected by the boosted voltage sensor and the reactor current detected by the current sensor, wherein failure of the current sensor is determined when a range of a variation of the reactor current detected by the current sensor is less than a predetermined current value and a range of a variation of the pre-boosting voltage detected by the pre-boosting voltage sensor exceeds a predetermined voltage value.
