摘要：
In the present invention, a first ceramic tube (10A) for a high-brightness discharge lamp has a light-emitting unit (12) that emits light therewithin and an electrode-sealing first tubule (14a) and second tubule (14b) respectively formed integrally to the two ends of the light-emitting unit (12). Of the light-emitting unit (12), a position towards the first tubule (14a) is provided with a through-hole (16) wherein the direction from the inside of the light-emitting unit (12) to the outside of the light-emitting unit (12) is the same as the direction of extension of the first tubule (14a).
