Claims

[Scope of utility model registration request]

(1) comprising a conductive terminal that is formed on the inner wall of the neck portion and electrically contacts an internal conductive film to which a high voltage is applied; and a spacer that supports the electron gun structure disposed within the neck portion; The spacer has a tip portion facing the inner wall surface of the neck portion, and has a hardness substantially equal to that of the neck glass;
A cathode ray tube characterized in that an insulator having substantially the same thermal expansion and coefficient as the spacer is fixed, and a tip end side of the spacer is set apart from the internal conductive film.

(2) the insulator is substantially the same as the neck glass;
2. The cathode ray tube according to claim 1, which is a mixed glass obtained by mixing powdered glass with low melting point glass in an appropriate proportion.
