Abstract
A flange portion is integrally formed with a stem which forms a sealing envelope for a gas discharge tube. Accordingly, operation for building and fixing the flange portion is not necessary, so that lamp assembly operation is simplified, and mass production is facilitated. In addition, when a gas discharge tube is to be fixed to an external stem setting portion, lamp setting is enabled at higher precision by utilizing positioning holes formed in the flange portion in advance.
