Abstract

PURPOSE: To prevent the fluctuation of height of three pairs of supporting member by securing an insulation board to the fixed side supporting member then setting dimension from referential face or the surface of insulation board through pressure molding.
CONSTITUTION: Supporting members 3, 4 at fixed side and movable side are secured to the insulation board 1, then it is pressure molded from above to set the height from the insulation board 1 to predetermined one. Then a filament 13 is stretched between fixed side supporting member 3 and resilient member 14. Thereafter basic metal board 11 is secured approximately at the center of filament 13, and electron emission material 12 is coated on said board 11. Cosequently direct heating complex cathode structure equipped with three pairs of filaments 13 having same height is obtained.
