摘要： A light source device (20;40) is provided. The light source device (20;40) comprises a semiconductor light-emitting element (12); and a wavelength conversion member (21;41) for converting a wavelength of a light emitted from the semiconductor light-emitting element (12). The semiconductor light-emitting element (12) has a light-emitting peak wavelength of not less than 380 nanometers and not more than 420 nanometers. The light emitted from the semiconductor light-emitting element (12) has a light energy density of not less than 0.2kW/cm 2 . The wavelength conversion member (21;41) contains at least one fluorescent substance selected from the group consisting of a (Sr 1-x Ba x ) 3 MgSi 2 O 8 :Eu 2+ (0≤x≤1) fluorescent substance, a (Y 1-y Gd y ) 3 (Al 1-z Ga z ) 5 O 12 :Ce 3+ (0≤y 3+ -activated fluorescent substance. The light source device (20;40) has a high output and a high light-emitting efficiency.
