A strobe device of the present invention includes a flash discharge tube having an anode electrode and a cathode electrode on both ends thereof, and a conductive reflector in contact with an outer peripheral surface of the flash discharge tube. The reflector houses a part of the flash discharge tube inside, and functions as an external trigger electrode. The reflector has a bottom that is in contact with a portion of the outer peripheral surface of the flash discharge tube, the portion covering at least an area between the anode electrode and the cathode electrode and a sintered metal of the cathode electrode. This can suppress variation in discharge path at every light emission from the flash discharge tube. As a result, variation in light quantity and variation in light distribution of light emitted from the strobe device can be suppressed.
