This fluorescent lamp is provided with at least one groove 1a having a substantially rectangular wave shape in plan view. It is configured by stacking two molded glass plates 1b that are stacked together, and the four sides that are in the vicinity of the outer peripheral ends of the stacked two molded glass plates 1b are sealed by frit to form a valve 1 that is an airtight container. In this way, the groove 1a forms a discharge path, electrodes are provided at both ends of the discharge path, and a discharge gas is sealed inside.

って、蛍光ランプが重くなるという問題点があった。However, in the fluorescent lamp shown in the first conventional example configured as described above, the bulb 1 is fritted on the four sides of the two glass plates 1b near the outer peripheral ends. Since the structure is formed by sealing, the two glass plates 1b are overlapped and placed in an electric furnace or the like, and the temperature is gradually raised to melt the frit to bond the two glass plates 1b. After that, there is a problem that the temperature needs to be gradually lowered and the powder is taken out, which takes time to manufacture and the manufacturing cost becomes high. Also, 2
The glass plates 1b are superposed on each other to form one tubular discharge path having a substantially rectangular wave shape in a plan view, and since the glass plate 1b is only superposed on the partition wall portion, If it is made thin, a gap is created, and the discharge may not pass through the proper passage and may be short-circuited through the partition wall. Therefore, it is necessary to secure the width of the partition wall to a predetermined width or more, and the fluorescent lamp becomes heavy. There was a point.

Although the valve 1 can be manufactured, there is a problem that it cannot be manufactured at high speed by machining.
