An inverter device and a motor driving device are arranged to have an inrush current limiting circuit (20) for preventing inrush current from being flown in a smoothing circuit (7) when the power is turned on. The inrush current limiting circuit (20) includes a current-limiting means (3), a plurality of semiconductor switching elements (4a,4b), an inrush limiting circuit driving circuit (30) for driving the semiconductor switching elements (4a,4b), and the semiconductor switching elements (4a,4b) being connected in parallel to each other.
