Abstract
A semiconductor light-emitting device (A) having a simple configuration whereby it is possible to easily and accurately confirm whether or not ultraviolet light is being emitted, the semiconductor light-emitting device comprising: a semiconductor light-emitting element () for emitting ultraviolet light in an ultraviolet or deep ultraviolet region; a cap part () having a through-hole () in the top part through which ultraviolet light passes and encircling the semiconductor light-emitting element (); a translucent cover () for transmitting ultraviolet light, the translucent cover being disposed so as to hermetically close up the through-hole (); and a UV-excited phosphor () which is excited by ultraviolet light and which emits visible light, the UV-excited phosphor being disposed inside the cap part ().
