PURPOSE:To eliminate the getter replacement at the neck regeneration and effectively suppress the discharge current by fixing a plurality of getters to either one of a frame, a magnetic shield, or a funnel inner surface before welding a panel to the funnal. CONSTITUTION:A panel 1 and a funnel 2 are welded through glass powder 3. A magnetic shield 6 is connected to a frame 5 and extended to a cone section 2a. The cone section 2a inner surface is coated with a conductive film 7 and a high-resistance film 8, and the neck section 2b inner surface is coated with a conductive film 9. Two metal support pieces 23 are extended to the cone section 2a from the frame 5, and getters 24 are fixed to tips of support pieces 23. Getters 24 are fixed to support pieces 23 before the welding of the panel and funnel, and they are processed so as to withstand the temperature change during the welding process. Thereby, the getter replacement at the neck regeneration is eliminated and the discharge current can be effectively suppressed. |
