A DC/DC converter in which a both-end voltage of each of capacitors can be safely uniformalized while an over current, which is passed through between the capacitors composing the DC/DC converter, is prevented. In a DC/DC converter which includes a plurality of switching elements, a reactor, a low-voltage side capacitor, a high-voltage side capacitor, a charge-discharge capacitor, and a controller which drives and controls the switching elements, the controller performs soft start control in which a duty ratio of at least one of the switching elements is gradually varied from 0% to 100%, and the switching element, in which the soft start control is not performed during the term of the soft start control, is turned off.
