Abstract:
A discharge tube includes a reflective film formed on an outer periphery of a cylindrical glass bulb by metal deposition. The reflective film is deposited in a range of 240° or more in the circumferential direction, and the range being larger in a center part than at each end in the axial direction. A stroboscopic device is equipped with this discharge tube.
