PROBLEM TO BE SOLVED: To provide an illuminator and a photographing device equipped with the illuminator capable of realizing the miniaturization of whole shape, the improvement of light condensing efficiency, the reduction of the number of component parts and the reduction of cost and obtaining stable optical characteristic, and in particular to provide a illuminator suitable for a still camera and a video camera or the like and the photographing device using it. SOLUTION: In this illuminator equipped with a discharge tube of a transparent body, there are constituted a discharge space for emitting luminous flux and a condensing optical system for controlling the flux distribution of a light component advancing nearly in the optical axis direction out of the luminous flux emitted from the discharge tube in a hermetically sealed space region formed inside the discharge tube, and the photographing device equipped with the illuminator is constituted.
