Abstract

See full text

An ultraviolet light emitting device having high quality and high reliability is provided by preventing deterioration of electrical characteristics which is associated with an ultraviolet light emission operation and caused by a sealing resin. The ultraviolet light emitting device is an ultraviolet light emitting device including: an ultraviolet light emitting element (2) formed of a nitride semiconductor; and an ultraviolet-transparent sealing resin (3) covering the ultraviolet light emitting element (2), wherein at least a specific portion (3a) of the sealing resin (3), which is in contact with pad electrodes (18) and (17) of the ultraviolet light emitting element (2), is a first type amorphous fluororesin, and a terminal functional group of a polymer or a copolymer that forms the first type amorphous fluororesin is a nonreactive terminal functional group which is not bondable to a metal that forms the pad electrodes (16) and (17).
