Abstract
The gas discharge tube in accordance with the present invention comprises at least two electrically conductive aperture members disposed within a thermoelectron transmission path between a cathode and an anode, and an insulator for electrically insulating the electrically conductive aperture members from each other, thereby being able to emit light with a high luminance. Its startability at the time of emitting light can be enhanced in particular when the aperture area of the electrically conductive aperture member on the downstream side in the thermoelectron transmission path is set favorably.
