Zusammenfassung:To stabilize light output of a flash lamp.SOLUTION: A flash lamp 1 comprises a bulb which has a stem 11, a conductive linear member 15 which penetrates the stem 11, and a conductive linear member 16 which penetrates the stem 11. The conductive linear member 15 comprises a lead part 51 and a cathode 52 provided atop of the lead part 51, and the conductive linear member 16 comprises a lead part 61 and an anode 62 provided atop of the lead part 61, in which the cross-sectional area of the cathode 52 crossing a Z direction is different from the cross-sectional area of the lead part 51 crossing the Z direction, and the cross-sectional area of the anode 62 crossing the Z direction is different from the cross-sectional area of the lead part 61 crossing the Z direction. The cathode 52 comprises a first projection part protruding in an internal space S and a first embedded part embedded in the stem 11, and the cathode 62 comprises a second projection part protruding in the internal space S and a second embedded part embedded in the stem 11.SELECTED DRAWING: Figure 2 【課題】フラッシュランプの光出力を安定化させること。【解決手段】フラッシュランプ1は、ステム11を有するバルブと、ステム11を貫通する導電性線状部材15と、ステム11を貫通する導電性線状部材16と、を備え、導電性線状部材15は、リード部51と、リード部51の先端に設けられたカソード52と、を備え、導電性線状部材16は、リード部61と、リード部61の先端に設けられたアノード62と、を備え、カソード52のZ方向と交差する断面積は、リード部51のZ方向と交差する断面積と異なり、アノード62のZ方向と交差する断面積は、リード部61のZ方向と交差する断面積と異なり、カソード52は、内部空間Sに突出する第1突出部と、ステム11に埋設される第1埋設部と、を備え、アノード62は、内部空間Sに突出する第2突出部と、ステム11に埋設される第2埋設部と、を備える。【選択図】図2
