A fluorescent character display tube has an anode base plate, a frame, a filament supporting member, and a fixing layer. The frame is provided above the anode base plate and the filament supporting member is welded on the frame. The fixing layer is provided between the frame and the anode base plate such that the frame is securely and air-tightly fixed to the anode base plate. The fixing layer may be a low melting point glass layer or a high heat-resistant resin. The high heat-resistant resin may be polyimide. The arrangement enables to reducing the vibration of the frame thereby reducing the noise.
