PROBLEM TO BE SOLVED: To provide an ultraviolet light irradiation device that can uniformly irradiate ultraviolet light even when the irradiated target has a curved surface.SOLUTION: An ultraviolet light source is provided with a fluorescence layer including a fluorescence material that irradiates ultraviolet light. There are provided: a plurality of electric discharge thin and long tubes filled with electric discharge gas; a thin film sheet provided in parallel with the plurality of electric discharge thin and long tubes; at least a pair of electrodes provided between the thin film sheet and the electric discharge thin and long tubes, and generating the electric discharge inside the electric discharge thin and long tubes; and a control circuit for controlling so as to apply electric voltage to the pair of electrodes to irradiate the ultraviolet light from a predetermined position. The pair of electrodes are provided so as to be substantially orthogonal to the plurality of electric discharge thin and long tubes in a longitudinal direction, and a holding body is made elastic. The imaged image in the image regions is divided into a plurality of images, and a designation of an ultraviolet light irradiation region corresponding to each of the divided images is received on a screen where the imaged image is displayed.SELECTED DRAWING: Figure 7 |
