PROBLEM TO BE SOLVED: To provide a flash light source device which can be miniaturized.SOLUTION: A flash light source device 1A includes a flash lamp 10, a wiring board 30, and a power supply unit 60. The flash lamp 10 has: a sealed container 11 which has a light transmission window provided on one end surface thereof and in which a discharge gas is sealed; a cathode and an anode for generating an arc discharge in the sealed container 11; and a lead pin projecting from the other end surface of the sealed container 11. The wiring board 30 has a main surface 31 and a rear surface 32. The lead pin of the flash lamp 10 arranged facing the main surface 31 is conductively bonded and fixed to the wiring board 30. The power supply unit 60 performs the charge and discharge of a current to be supplied to the flash lamp 10. The power supply unit 60 has a chip capacitor 61 surface-mounted on the wiring board 30.
Abstract:
