Abstract: There are provided a glass tube in which a rare gas under predetermined pressure is sealed, a cathode electrode and an anode electrode disposed in a first end portion and a second end portion of the glass tube, respectively, facing each other, and a trigger electrode including a transparent conductive film formed on an outer peripheral surface of the glass tube. The trigger electrode includes an electrode body disposed on the outer peripheral surface of the glass tube, along a tube axis direction of the glass tube, and an enlarged portion that covers at least any one of the cathode electrode and the anode electrode, and that has a circumferential width wider than a circumferential width of the electrode body. This provides a flash discharge tube capable of reducing variations in optical distribution characteristics during light emission with a small amount of light, and improving life durability during continuous emission of a large amount of light and at short intervals.
