In an anode-side assembling process, a first end of a glass tube is fused to a rearward end of an electrode bar secured to an anode-side lead to produce a primary sealed product. In a cathode-side assembling process, a ring-shaped cathode is secured by caulking to a forward end portion of an electrode bar secured to a forward end of a cathode-side lead to produce a cathode member. In an assembling process, a second end of the glass tube of the primary sealed product is fused to a rearward end of the electrode bar secured to the cathode-side lead of the cathode member to produce a xenon discharge tube. A trigger electrode, which is composed of a transparent conductive film, is formed on a surface of the glass tube so that the light-transmissive sealed tube-coating ratio specified by the transparent conductive film is within a range of 5 to 30%.
A method for producing a flash discharge tube comprising a trigger electrode composed of a transparent conductive film formed on a surface of a light-transmissive sealed tube, said method comprising the steps of:
