Abstract: In a flash lamp 1, a front end part 62 of a cathode 60 and a front end part 72 of an anode 70 are opposed to each other on a reference line RL, and with respect to a reference surface RS including the reference line RL, a front end part 82 of a trigger electrode 80 is located on one side, and a front end part 92 of a trigger electrode 90 is located on the other side. Further, a terminal end 82a of the front end part 82 of the trigger electrode 80 and a terminal end 92a of the front end part 92 of the trigger electrode 90 are separated from the reference line RL, and each front end part 82, 92 is formed so as to taper toward the reference line RL. Accordingly, an arc discharge occurs in a limited route R from a terminal end portion of the front end part 62 of the cathode 60 through a terminal end portion of the front end part 82 of the trigger electrode 80 and a terminal end portion of the front end part 92 of the trigger electrode 90 to a terminal end portion of the front end part 72 of the anode 70.

Abstract translation: 在闪光灯1中，阴极60的前端部62和阳极70的前端部72在基准线RL上彼此相对，并且相对于包括基准线RL的基准面RS， 触发电极80的前端部82位于一侧，触发电极90的前端部92位于另一侧。 此外，触发电极80的前端部82的终端82a和触发电极90的前端部92的终端92a与基准线RL分离，前端部82,92为 形成为朝向基准线RL逐渐变细。 因此，在从触发电极80的前端部82的端子部分到阴极60的前端部分62的末端部分的前端部分的终端部分的限制路径R中发生电弧放电 触发电极90的端部92连接到阳极70的前端部分72的终端部分。
