摘要

A cold cathode discharge tube comprising a glass tube (1) and a bottomed cylindrical external terminal (2) fitted into the end part of the glass tube. An introduction wire (4) connected to an electrode (3) positioned in the glass tube is passed through a hole (2b) formed in the bottom part (2a) of the external terminal, and welded to the external terminal on the outside of the hole. A filler (6) is filled in a clearance between the external terminal and the glass tube to increase the strength of the external terminal.
