A flash device includes a DC power supply, a flash lamp, and a plurality of charge/discharge elements, which are charged via a charging path by the DC power supply and discharge electric charge via a discharging path to the flash lamp. A first switch selectively establishes (a) a parallel state in which the charge/discharge elements are connected in parallel with one another, and connected to the DC power supply via the charging path and (b) a series state in which the charge/discharge elements are connected in series with the flash lamp via the discharging path, and connected in series with one another. A second switch is positioned in the charging path between the DC power supply and the charge/discharge elements, and selectively connects and disconnects the charge/discharge elements to and from the DC power supply. A controller has the second switch perform connection and has the first switch establish the parallel state to have the charge/discharge elements charged. The controller has the second switch perform disconnection and has the first switch establish the series state to have the flash lamp emit light.
