PURPOSE:To make a unit compact by forming a reflecting layer, by which flash is reflected, on the wall of a flash lamp tube, opposite to the open surface of the tube. CONSTITUTION:A reflecting plate 6 formed so as to cover the wall of a flash lamp tube 1 is mounted on the wall of the tube 1, opposite to the open surface 3. By the reflecting plate 6, a reflecting layer is formed. Forming of electric-conductive reflective surface in the reflecting part of the back side of the flash lamp tube is not necessary, and flash lamp tube 1 and a reflecting part 2 can closely be arranged. Therefore, the reflecting part 2 is made small and a unit is made compact. |
