A DC-DC converter, which is configured to step down a direct current voltage and then outputs to a load, the DC-DC converter comprising: a switching device that converts the direct current voltage into an alternating current voltage; a rectification unit that rectifies the alternating current voltage; an output capacitor that is connected in parallel with the load, and a smoothing inductor comprising a plurality of divided inductors connected in series, wherein at least one of the number of windings and the number of layers of respective windings of the divided inductors of the smoothing inductor is adjusted so that a sum total of inductances of the divided inductors become a desired inductance and so that a sum total of floating capacitances of the plurality of the divided inductors is smaller than a floating capacitance of single inductor having an equivalent inductance.
