れていることを特徴とするセラミツク放電灯。 In a ceramic discharge lamp equipped with an arc tube formed by sealing the opening of a translucent ceramic tube with a ceramic closure that supports an electrode, the ceramic closure has a small-diameter conductive ceramic part and a large-diameter non-conductive ceramic part. The opening of the translucent ceramic tube is hermetically sealed by solid phase bonding so that the non-conductive ceramic section is located on the outside, and the conductive ceramic tube is laminated with a conductive ceramic section. An electrode is fixed to one surface of the part, and an introduction body is fixed to the other surface of the part, and the introduction body penetrates the non-conductive ceramic part and is led out to the outside. discharge lamp.
