Abstract
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.
