ABSTRACT:
A glass pipe80for a discharge lamp is prepared which includes a luminous bulb portion1′that will be formed into a luminous bulb of a high pressure discharge lamp and a side tube portion2′. Subsequently, a glass member70made of a second glass having a softening point lower than that of a first glass constituting the side tube portion2′is inserted into the side tube portion2′, after which a getter75is disposed in the side tube portion2′. Then, with the pressure inside the glass pipe80reduced, the side tube portion2′is heated to tightly attach the glass member70to the side tube portion2′, thereby forming a sealing portion.
