Abstract (en)

A discharge tube 10 including a pair of electrodes 14a, 14b arranged in opposed relation to each other with an insulating member 12 between them is disclosed. In order to provide a discharge tube capable of producing a stable break-down voltage even against a surge voltage with a short rise time, a coating material 16 containing at least one alkali metal salt including potassium bromide, potassium fluoride and sodium fluoride of 0.01 to 60 wgt % is applied on the discharge surfaces of the electrodes 14a, 14b. <IMAGE>
