Claims

[Scope of utility model registration request]

In an image pickup tube in which an electron gun and an evaporative getter structure are provided inside the bulb and an electrode for electrostatic deflection is formed on the inner wall of the bulb, an evaporative getter support formed in a ring shape and having a height on the outer circumference larger than the height on the inner circumference is used to 1. An imaging tube, characterized in that it is disposed in a space between a gun and an exhaust pipe provided on a stem, and is fixed so that the direction of scattering of the evaporative getter is on the side of the exhaust pipe.
