An electronic flash unit of the dynamic flat flash type includes a flash control circuit which produces a flash termination signal by detecting the fact that a value associated with pulse flashes reaches a predetermined level and further produces a flash resumption signal within a period of time less than the deionization time of a flash discharge tube after the flash termination signal has been produced. With the flash control circuit, the electronic flash unit permits the discharge tube to repeatedly emit a pulse flash during an exposure operation of a shutter of a camera so that the flash characteristics substantially equivalent to a continuous flash can be obtained.
