An ultraviolet emitting device according to the present disclosure includes a lamp for mounting a discharge gas and an ultraviolet emission source therein, and a plurality of yarns formed by extending and aggregating carbon nanotubes in a first direction, and includes a first electrode at least partially exposed to the discharge gas within the lamp. Accordingly, electron emission efficiency of the first electrode is improved to achieve high efficiency, and durability is also improved to provide a long-life device.
