Abstract

PURPOSE:To prevent intermittent discharge due to beam leak by forming the first metal vapor coating which surrounds insulating support material in response to the grid, and the second metal vapor coating inside the neck. CONSTITUTION:Insulating support material 367 in response to the fourth grid 364 is surrounded, and wire-shaped and plate-shaped vapor coated metal 44 to contact the fourth grid is provided, in the assembling process, the metal wire 44 is vaporized by high frequency, etc. through the outside of the neck 35, the first metal vapor 45 to contact the fourth grid, and the second metal coating 46 are provided inside the neck 35 in response to the first coating 45. Partial electric potential at the inner wall of the neck 35 and at the insulating support material 367 is prevented from rising by providing these first and second coatings 45, 56, even if applied voltages of the third and fifth grids 363, 365 become high, they serve as electric field shield, so that intermittent discharge due to beam leak from the fourth grid 364 can be obstructed.
