ことを特徴とする車両用放電灯。[Claims for Utility Model Registration] 1. A discharge lamp bulb comprising a pair of main electrodes and a starting electrode installed close to one of the main electrodes connected to the ground; a high voltage generation circuit that generates a voltage that sustains the discharge between the electrodes; and a high voltage generation circuit that is connected between the high voltage generation circuit and the starting electrode and that is necessary for causing dielectric breakdown between the starting electrode and the earth-side main electrode. A discharge lamp for a vehicle, comprising: a starting circuit that applies a voltage equal to or lower than a sustained voltage to the starting electrode. 2. The vehicular discharge lamp according to claim 1, wherein the starting circuit includes a starting switch interposed between the high voltage generating circuit and the starting electrode, and closes the starting switch at the time of starting to prevent discharge between the main electrodes. A discharge lamp for a vehicle, comprising a switch control circuit that opens a start switch when discharge starts and continues to be maintained.
