Abstract: PURPOSE:To decrease the number of parts used, simplifies the manufacturing processes, reduce risk of deterioration of a cathode-ray tube in its degree of vacuum, and provide practicability of performing getter flash uniformly by fixing a getter vessel accommodating getter directly to a specified place of the funnel inner wall by the use of inorganic adhesive. CONSTITUTION:A getter vessel 2 accommodating getter 1 is fixed directly to a specified place on the inner wall of a funnel 3 using inorganic adhesive 4. This allows omission of any intermediate getter structure and a getter support to which the getter structure is secured. Further the getter vessel 2 can be fixed any desired to the inner wall of the funnel 3 in its place where getter flash can be made uniformly. This permits reduction of the number of parts used and simplifies the manufacturing processes. Lesser number of parts used signifies less origins of gas emission, which decreases fear of deterioration of a cathode-ray tube in its degree of vacuum.
