The flash light emitting device has a mechanism in which flash light emitted from a cylindrical arc tube is reflected by a reflecting shade mounted so as to surround the arc tube, and the reflected light is irradiated toward the subject. As a method of improving the irradiation amount from this flash light emitting device, there is a method of increasing the capacity of a main capacitor that supplies electric power to the arc tube to increase the amount of flash light emitted from the arc tube. There is a problem in that it is costly to prepare a capacitor and the size becomes large.

In this regard, JP-A-13-318409
No., without changing the amount of flashlight emitted from the arc tube,
A method is described in which a reflecting shade efficiently reflects flash light to increase the irradiation amount of the reflected light toward the subject. The reflective shade used in this method is formed with a curve that opens wider toward the subject (front side) and has a convex portion toward the subject at the base portion (the innermost side) that contacts the arc tube. . The reflection shade and the arc tube are in line contact with each other in the extending direction of the arc tube at the convex portion. By using the reflective shade having such a shape, the flash light emitted from the arc tube is efficiently reflected by the reflective shade, and the irradiation amount of the reflected light toward the subject can be increased.
