る。 The present invention will be explained below with reference to FIG. In the figure, the same reference numerals as in FIG. 2 indicate the same parts, and the explanation will be omitted. In the present invention, the leg piece 12a of the support spring 12 that contacts the conductive film 7 and the getter container 13 are connected to each other using a thin metal wire 16.
The electron gun 4' is fixed by bringing the tips of the legs 12a close to each other so that the tips of the legs 12a are in slight contact with the inner circumferential surface of the neck portion 3 or not at all. It is characterized in that the thin metal wire 16 is sealed in the neck part 3 and cut after being evacuated.

することができる。 This electron gun 4' is supported by the other leg piece 12b of the support spring 12 until it is inserted into the neck portion 3 and sealed. After the enclosing and evacuation, the getter container 13 is heated by induction heating from the outside of the neck part 3 to flash the getter and the thin metal wire 1
6, the leg piece 12a can be brought into contact with the inside of the neck part 3 as shown in FIG. 4, and electrically connected to the conductive film 7.

In addition, since the conductive film 7 is not rubbed and peeled off, there is no discharge inside the bulb or poor light emission.Furthermore, the elastic force of the support spring 12 can be made stronger than before, so it is easy to support the electron gun 4' and connect the conductive film 7. Ensures electrical connection.
