(Unexamined Japanese Patent Publication No. 62-90844
Publication No.). In addition, four straight discharge tubes are connected to each other,
Among these, a fluorescent lamp is also known in which electrodes are provided at the ends of two discharge tubes, and a cap is also provided (Japanese Patent Laid-Open No. 62-21
Publication No. 7526). Such a plurality of straight discharge tubes are communicated with each other in the following manner. That is, after heating and softening the communication planned portions of glass tubes that are to become a plurality of straight discharge tubes, air is introduced into the glass tubes through exhaust pipes provided at the ends of the glass tubes, thereby forming the communication planned portions. In this method, a plurality of glass tubes are connected by blowing out each glass tube to form a bulge in each portion, and welding the bulges to each other (Japanese Unexamined Patent Publication No. 133730/1982).

ン５が設けられている。As shown in the figure, the fluorescent lamp according to the embodiment of the present invention includes two straight discharge tubes 1.2 arranged close to each other in parallel.
A first discharge tube 1 and a second discharge tube 2 are connected by a connecting portion 3. Thereby, the discharge tubes 1.2 are communicated via the connecting portion 3. One end of the discharge tubes 1 and 2 is closed, and a stem is sealed at the other end, and a pair of lead wires are implanted in each of the stems, and an electrode is held between each lead wire. . Further, the discharge tubes 1 and 2 have a phosphor film formed on the inner surface of the glass tube, and mercury and a rare gas are sealed inside the phosphor film. A cap 4 is fixed to one end of the discharge tube 1.2. Four terminal pins 5 are provided on the bottom surface of the cap 4.
そして、放電管１，２の連結部３および頂部の外面には
