Abstract:
1. A strobe device comprising a tube having rare gas enclosed therein and having a light-transmitting property, and a reflector formed in a box shape into which the tube is housed, wherein: the tube includes the reflector has a surface at least partially having electric conductivity, has a front-surface opening portion provided on a front surface of the reflector and configured to be opened so that at least part of a side surface of the tube is exposed, and has a side-surface opening portion provided on a side surface of the reflector at the cathode side and configured to be opened so that the another end of the tube projects outwardly; the reflector is configured such that the cathode-side end of the surface having electric conductivity is formed to be positioned closer to the anode side than the electron source; and the reflector includes an electrically-conductive projecting portion configured to project from the cathode-side end of the surface having electric conductivity so as to be closer to the cathode side than the anode-side end of the electron source.
