PROBLEM TO BE SOLVED: To avoid a bad influence to be exerted on a work by alleviating the heat of reaction of an ultraviolet-curable resin. SOLUTION: The subject ultraviolet emitting apparatus is provided with: one or more head parts 120 each having one or more semiconductor devices each of which can emit an ultraviolet ray as an ultraviolet ray source; a controller part 110 provided with a control part 114 capable of setting the individual ultraviolet emitting conditions of the head parts 120 and a power source part 112 for supplying a driving current to each of the semiconductor devices; and a cable part 130 provided with electrical signal wires for connecting the head parts 120 electrically to the controller part 110. The control part 114 controls the ultraviolet ray emitted from each of the semiconductor devices to be pulsed so that the calorie generated when the ultraviolet-curable resin is cured is restrained from exceeding the allowable calorie of an object being the work and ascending moreover.
