PROBLEM TO BE SOLVED: To provide a flash light generation circuit capable of attaining the reduction of a cost and the reduction of a substrate circuit area. SOLUTION: The primary side coil 16-3a of a trigger coil 16-3 is arranged together with a light emitting tube 16-1 in a discharge loop L1 where a power emitted from a main capacitor 13 flows, and the voltage of a built-in battery 1 is increased up to a prescribed voltage by a booster circuit 11, and the power is accumulated in the main capacitor 13 and a trigger capacitor 16-2, then, a trigger switch 15 is closed so that the current may flow in the primary side coil 16-3a, and then, the light is emitted from the light emitting tube 16-1 by a trigger voltage from the secondary side coil 16-3b. |
