Claims

[Claims for Utility Model Registration] A glass enclosure consisting of a light emitting space surrounding section and a sealed tube section following it, where the open end of the enclosed tube section is located within the sealed tube section and the outer end of the sealed tube section. a bottomed cylinder made of glass arranged to face the side; an external lead rod inserted into the cylindrical hole of the bottomed cylinder; and an external lead rod extending from the outside of the bottom wall of the bottomed cylinder into the light emitting space surrounding section. an internal lead rod arranged as shown in FIG.
a conductive holding plate to which the base end of the internal lead rod is fixed; and a conductive holding plate extending along the outer periphery of the bottomed cylinder, one end of which is electrically connected to the holding plate, and the other end of the holding plate being connected to the external lead rod. and a strip-shaped metal foil electrically connected to the holding plate, and the bottomed cylinder has a tapered outer circumferential surface in a circumferential wall portion that continues to the outer end surface of the bottom wall, and the retaining plate and the A light bulb characterized in that a metal thin film is interposed between the outer end surface of the bottom wall of the bottomed cylindrical body.
