    摘要： To provide a discharge tube having improved stability of operating voltage to repeated discharges. The discharge tube includes a cylindrical insulating hollow body 2 having openings at least at both ends and at least a pair of sealing electrodes 3 facing to each other for closing the openings so as to seal a discharge control gas inside the body, wherein a discharge trigger film 4 made of a conductive material is formed on the inner circumferential surface of the insulating hollow body, each of the sealing electrodes has a convex portion 3a projecting into the insulating hollow body and a discharge active layer(s) 5 that is/are made of a material having higher electron emission characteristics than that of the sealing electrodes and formed at the apical end of the convex portion, the discharge active layer(s) is/are formed at the apical end of the convex portion and near the outer periphery edge of the apical surface as a plurality of layers or a continuously extending single layer along the outer periphery edge, and the central part of the apical surface of the convex portion is a region where the discharge active layer is not formed.
