ABSTRACT:
An anode button for a cathode ray tube comprises an outer cup having a peripheral wall made so thin as to be well sealed to a glass bulb and an inner cup disposed in the outer cup for minimizing X-ray leak. A space is provided between the outer and inner cups so that the seal between the outer cup and the glass bulb is not damaged.
