放電灯。 The openings at both ends of the arc tube bulb made of translucent ceramics are each sealed with closing bodies made of conductive ceramics, and the base end of the electrode is embedded in the inner surface of each closing body, and the external introduction body is buried in the outside surface of each closing body. In the fixed ceramic discharge lamp, at least one opening of the arc tube bulb is sealed with a disc-shaped closing body having a smaller diameter than the inner diameter of the opening through a glass solder, and
The electrode and the external introducing body are arranged coaxially along the central axis of the arc tube, and the part buried in each of the closing bodies is deformed and bent so as to increase the contact area with the closing body. A ceramic discharge lamp characterized by:
