A hot air spraying nozzle and an apparatus for melting an opening part of a tube including the hot air spraying nozzle is provided to prevent wrinkle generated on a location except a heat molten area by accurately melting the heat molten area of the tube. An apparatus(200) for melting an opening part of a tube(1) including the hot air spraying nozzle comprises a heating unit(110), a spraying nozzle, a socket member(130), a supporting unit(140), a hot air supply unit(150), a hot air exhaust unit(160), and a cooling unit(170). The heating unit heats air and generates hot air. The spraying unit sprays the hot air to an opening(1a) of the tube. The socket member is coupled to the spraying nozzle. The supporting unit is coupled to an outer circumference of the socket member. The hot air supply unit supplies the spraying nozzle with the hot air. The hot air exhaust unit exhausts the hot air through the socket member to outside. The cooling unit cools the sprayed hot air.
