An ultraviolet irradiating apparatus is provided to control power supplied to each light emitting diode by disposing an ultraviolet light emitting diode of a line type as an ultraviolet source for forming a light irradiation region of a thin and long shape emitted from an ultraviolet irradiating apparatus and by independently supplying power to each ultraviolet light emitting diode. An ultraviolet irradiating apparatus includes an ultraviolet irradiating part(10) for irradiating ultraviolet rays, a power part for supplying power to the ultraviolet irradiating part, and a control part for supplying a control signal to the power part. The ultraviolet irradiating part includes a plurality of ultraviolet light emitting diode and a plurality of convex lenses(13). The plurality of ultraviolet light emitting diodes are disposed in parallel with each other on a print substrate(12), made of a line type. The plurality of convex lenses are disposed at the light emitting part of the plurality of ultraviolet light emitting diodes, corresponding to each ultraviolet light emitting diode. Power is independently supplied from the power part to the plurality of ultraviolet light emitting diode, and the power is controlled by the control part. A cylindrical lens(15) is installed at the light emission part of the convex lens, collecting the light collected by the convex lens in one direction.
