An inverter device includes a DC power supply, an inversion section connected via a DC power supply line to the DC power supply to be supplied with DC voltage from the DC power supply, thereby delivering AC voltage, a current-detecting resistor connected to the DC power supply line and having both ends, and a current detector detecting current on the basis of voltage developed across both ends of the current-detecting resistor. The current detector includes a voltage-dividing resistor, connected between a level-shift power supply line having a predetermined level-shift voltage and one of the ends of the current-detecting resistor, the voltage-dividing resistor having a voltage-dividing point. The current detector further includes an A/D converter having a pair of reference potential terminals and an input terminal, one of the reference potential terminals being connected to the other end of the current-detecting resistor, the input terminal being connected to the voltage-dividing point of the voltage-dividing resistor.
