<p>A high pressure discharge lamp comprises a vessel (4a) made of a non-conductive material which forms an inner space filled with an ionizable light-emitting material and a starting gas, the vessel having first and second opening portions (5a,5b) at both ends thereof, and a non-conductive member inserted into the first opening portion of the vessel and having an outer diameter which is smaller than inner diameter of the first opening portion so as to form a gap between the vessel and the non-conductive member, the non-conductive member further having a hole. An electrode unit (17) is inserted into the hole of the non-conductive member, the electrode unit has a first end which is exposed to the inner space of the vessel, and a second end which is exposed to outside of the vessel. A starting electrode (8) is arranged in the gap between the vessel and the non-conductive member, and has a first end which is exposed to the inner space, and a second end which is exposed to outside of the vessel. The vessel, the non-conductive member and the starting electrode are an integrated body which has been formed by a co-firing process. <IMAGE></p> |
