<P>PROBLEM TO BE SOLVED: To provide a low-pressure discharge lamp wherein a discharge tube is appropriately fixed against a lamp base. <P>SOLUTION: A base cap (6) includes a tube opening part (10) in order to receive an end part of the discharge tube and an adhesive space (14) adjacent to the tube opening part and open toward the discharge tube, and the adhesive space houses a certain amount of adhesive. The adhesive adheres to the end part of the discharge tube, and fixes the discharge tube to the base cap including at least one upper side crossing component (31) and at least one lower side crossing component (32). The crossing components are substantially extended in a plane parallel to the plane of the tube opening part. These upper side and lower side crossing components at least partially restrict the adhesive space. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
