タルハライドランプ。 In a metal halide lamp that is used without an outer tube, the opening of a translucent ceramic tube containing a rare gas, mercury, and a metal halide is sealed with a ceramic closure that supports an electrode, and the ceramic closure is used without an outer tube. It is made by laminating a conductive ceramic part and a non-conductive ceramic part, and the opening of the translucent ceramic tube is hermetically sealed with glass solder so that the non-conductive ceramic part is located on the outside. An electrode is fixed to one surface of the conductive ceramic part, and an introduction member is fixed to the other surface, and the introduction member penetrates the non-conductive ceramic part via a glass solder and is led out to the outside. , a metal halide lamp characterized in that at least a portion of the introduction body is coated with an oxidation-resistant substance.
