    摘要: The formation step of a sealing portion 2 includes the substeps of inserting, into the side tube portion 2′, a glass member 70 made of a second glass having a softening point lower than that of a first glass constituting the side tube portion 2′; tightly attaching forward and backward portions (A and C) of the glass member 70 to the side tube portion 2′ by heating the side tube portion 2′ when the glass member 70 is divided into the forward portion, the backward portion, and a central portion under the assumption that the side of the glass member 70 closer to a luminous bulb portion 1′ is the forward side, thereby forming a cavity 30 between at least a portion of the central portion (B) and the side tube portion 2′; and heating, after the attachment step, a portion including at least the glass member 70 and the side tube portion 2′ at a temperature higher than the strain point temperature of the second glass.
