There is provided a light emitting diode drive apparatus which decreases a conducted emission. The light emitting diode drive apparatus includes a light emitting diode to which a voltage is applied from a voltage source, a choke coil connected in series to the light emitting diode, a rectifier diode connected in parallel to the light emitting diode and the choke coil to supply a back electromotive force generated in the choke coil to the light emitting diode, and a switching drive circuit including a switching element and a control circuit block. The switching element determines whether a current is applied or not applied to the light emitting diode. The control circuit block controls on/off timing of the switching element to control the current flowing into the light emitting diode. The choke coil is connected between the light emitting diode and the switching element.
