A light-emitting devicecomprises a base, a nitride semiconductor light-emitting elementflip-chip mounted on the base, and an amorphous fluororesin sealing the nitride semiconductor light-emitting element. The light-emitting devicecomprises a deformation-prevention layerfor preventing a shape change of an amorphous fluororesin by heat treatment after shipment of the light-emitting device, and the deformation-prevention layeris formed of a layer in which a thermosetting resin or an ultraviolet curing resin is cured, and the cured layer directly covers the surface of the amorphous fluororesin.

Light-emitting device

The ultraviolet light-emitting device includes a base, a nitride semiconductor ultraviolet light-emitting element flip-chip mounted on the base, and a lens for sealing a nitride semiconductor ultraviolet light-emitting element to focus or diffuse light emitted from the nitride semiconductor ultraviolet light-emitting device. The lens is composed of an amorphous fluororesin in which a structural unit of a polymer or copolymer has a fluorine-containing aliphatic cyclic structure and a terminal functional group is a perfluoroalkyl group, and a density of the amorphous fluororesin is higher than 2.11 g/cm.
