響を与えていた。As described above, in the conventional image pickup tube, the joint portion between the electrode 11 and the mesh electrode 16 is composed of an extremely large number of parts. Furthermore, most of the connections between component parts were done by spot welding, making the manufacturing process much more streamlined. As a result, not only does the number of man-hours for the work increase significantly, but also a large amount of dust is generated due to splashing during each work, particularly during spot welding, which adversely affects the characteristics of the image pickup tube.

Ｎ１２０と弾性支持材２１とを一体化してなる。An embodiment of the present invention will be described below with reference to FIG. Note that the same members as in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted. It is formed by integrating a support N120 for fixing the insulating material 12 to the electric wire 1#A11 and an elastic support material 21.

が可能となる効果がある。By fixing the elastic support material 21 to the electrode lit, the original purpose of the elastic support material 21 can of course be achieved, but it can also serve the function of fixing the insulating material 12, so the number of parts can be reduced, and The number of spot welding points for fixing to the electrode 11 is also greatly reduced, reducing the potential for dust generation due to splash, and reducing electrode deformation due to pot welding.
In addition, the number of work steps is significantly reduced, and as a result, the manufacturing process can be simplified by reducing the potential for splash generation due to spot welding, and the characteristics of the image pickup tube can be improved.
