Claims

[Scope of utility model registration request]

The electron gun unit includes a plurality of stacked ceramic insulating cylinders with metal electrodes interposed therebetween as an envelope of the electron gun unit, 2. The electron gun unit is housed in a metal case, and a high voltage is applied to the metal In an electron beam tube, a high voltage insulated wire is connected to the electrode from the outside of the case, and a gap between the electron gun section and the case is filled with a filler having good electrical insulation. A flexible second insulated wire having a thinner outer diameter than the high-voltage insulated wire is interposed between the metal electrode and the metal electrode, and one end of the second insulated wire is connected to the front,
The high-voltage insulated wire is connected to the outer circumference of the metal electrode by soldering or the like, and is taken out to the other end of the second insulated wire to the outside of the case. 1. An electron beam tube, wherein the electron beam tube is connected to the electron beam tube, and the gap is filled with a filler and hardened.
