Abstract:
To provide a flickerless discharge lamp which can remove hydrogen by a simple and safe means even if the lamp is a large discharge lamp with high pressure when lit, the discharge lamp has a pair of electrodes and a hydrogen getter (4) in the interior of an arc tube, the hydrogen getter (4) being formed of a container (41) made of metal which is hydrogen permeable and a hydrogen absorbent body (42) that is composed of a metal which can absorb hydrogen that is enclosed inside of the container (41) and is fixed to an inside wall of the container (41).
