Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a long-life, industrially usable flash lamp with its illuminance maintenance rate kept at a high level by using alumina (Al2O3) or sapphire (single-crystal alumina) for an arc tube, and to provide a flash lamp device using the flash lamp. SOLUTION: In the flash lamp comprising an arc tube made of alumina (Al2O3) or sapphire (single-crystal alumina), the concentration of Ti contained in the arc tube is set to 10 wt.ppm or less. Also, in the flash lamp device comprising the flash lamp and a feeder system wherein a pulse width at lighting of the flash lamp is 700 μs or less and irradiation energy is 43 kW/cm2or greater, the arc tube of the flash lamp is made of alumina (Al2O3) or sapphire (single-crystal alumina) and contains Ti at a concentration of 10 wt.ppm or less.
