PROBLEM TO BE SOLVED : To provide an ultraviolet light generating target capable of enhancing ultraviolet light generation efficiency, an electron beam-excited ultraviolet light source, and a method of producing an ultraviolet light generating target. SOLUTION : An ultraviolet light generating target 20 includes : a substrate 21 which transmits ultraviolet light UV; and a light-emitting layer 22 which is provided on the substrate 21 and receives an electron beam EB to generate the ultraviolet light UV. The light-emitting layer 22 contains a rare earth-containing aluminum garnet crystal which is powdery or granular and to which an activator has been added. The light-emitting layer 22 has an ultraviolet emission peak wavelength of 300 nm or less. COPYRIGHT : (C)2014, JPO&INPIT
