PROBLEM TO BE SOLVED: To provide a flash lamp lighting device free from damaging a charging circuit or the like even if a lamp breakage trouble occurs during lighting or a grounding trouble occurs. SOLUTION: In the flash lamp lighting device including at least a plurality of luminous circuits H<SB>1</SB>, H<SB>2</SB>to H<SB>N</SB>made by connecting in parallel series circuits consisting of flash lamps X<SB>1</SB>, X<SB>2</SB>to X<SB>N</SB>, inductances L<SB>1</SB>, L<SB>2</SB>to L<SB>N</SB>and capacitors C<SB>1</SB>, C<SB>2</SB>to C<SB>N</SB>supplying luminous energy to the flash lamps and a charging circuit I supplying charge current to each capacitor of the plurality of luminous circuits through a common diode D, damage of the diode D of the charging circuit can be prevented at a lamp breakage trouble during lighting or a grounding trouble during charging by providing a diode current limiting means Ry in series between the diode and each capacitor.
