Abstract: A sealing body (4) for a discharge lamp made of a functionally gradient material rich in nonconductive component on one side and rich in conductive component on the other side, and connected to a side pipe (3) connected to the arc tube (2) of the discharge lamp at the region rich in nonconductive component. An electrode core rod (7) having an electrode at one end is shrink-fitted in the sealing body (4). A tapered surface inclining with respect to the center axis of the discharge lamp is provided on the outer periphery side of the sealing body (4) in the region rich in nonconductive component in such a way that the maximum width B of the arc space side end face of the sealing body (4) is smaller than the maximum width M in the direction perpendicular to the axis of the sealing body (4) and larger than the diameter d of the electrode core rod (7). Thus, the variation of the pressure resistance of the sealing part is eliminated.

Abstract: PROBLEM TO BE SOLVED: To provide a bulb being less broken at a weld sealing end of a tube in a sealing process of an electric discharge lamp or an incandescent electric bulb or the like and in an assembling and fabricating process following the sealing process and a bulb using it. SOLUTION: This bulb sealing body 4 for sealing a tube 3 continuously provided at a light emitting tube 2 of a bulb, consists of a substantially columnar tilt function material formed of a conductive part 41 and an insulation part 40, and forms a groove part on an outer periphery successively to an outer end of a weld sealed part. Alternatively, a step is provided on the outer periphery so that an outer diameter of a part from the outer end of the welded sealing part outwardly is smaller than the outer diameter of the weld sealed part. Further, this sealing body 4 is used for a bulb.
