PROBLEM TO BE SOLVED: To realize versatility and life-prolongation of a flash lamp. SOLUTION: In the flash lamp in which a pulse lighting is carried out by sealing a rare gas in a quartz glass tube and providing electrodes at both ends, the quartz glass tube is made of quartz glass containing about 100 ppm to 200 ppm of OH group, and sterilization and curing with an ultraviolet ray or the like are carried out by increasing the peak current by making a supply voltage for the flash lamp at 1.5 kV to 3.0 kV, and by raising the luminous efficiency of emission spectra of 220 nm to 300 nm of the light of ultraviolet ray part.
