Abstract
A flash apparatus is provided with a flash tube of the point light source type, a reflector, and a diffuser panel. The reflector reflects light flux from the flash tube forward. The diffuser panel is placed in a light flux passing position in front of the flash tube and the reflector and diffuses the light flux from the flash tube. The diffuser panel is so formed that diffusion angles of the light flux can vary with positions between a center corresponding to a light-emitting axis of the flash tube to a periphery concerning an area where the light flux from the flash tube passes.
