Abstract
This invention provides a discharge tube which is small and easy to manufacture, which prevents the discharge characteristics from being disturbed by a grounded body located nearby, and which makes creeping discharges unlikely to occur and at the same time enhances the degree of freedom in incorporating the discharge tube into devices. The discharge tube of this invention has electrode plates fixed at the ends of the enclosure so that the electrode plates have their discharge electrodes protruding inwardly to face each other. The central portion of one of the electrode plates is bulged outwardly, and the discharge plane of the discharge electrode is located close to a plane including the periphery of the electrode plate.
