| 英文摘要 | Provided is an ultraviolet light emitting device that prevents peeled off of a non-bonding amorphous fluororesin and has high quality and high reliability. An ultraviolet light emitting device 1 in which a nitride semiconductor ultraviolet light emitting element 10 including a sapphire substrate 11 flip-chip mounted on a base 30 is sealed with an amorphous fluororesin 40, in which the rear surface of the sapphire substrate 11 has a polished surface having an epitaxial growth grade, or a roughened surface having an arithmetic average roughness Ra of 25 nm or more, a structural unit of a polymer or copolymer constituting the amorphous fluororesin 40 has a fluorine-containing aliphatic cyclic structure, a terminal functional group of a polymer or copolymer constituting the first resin portion that is in direct contact with the light emitting element 10 in the amorphous fluororesin 40 is a perfluoroalkyl group, and when the rear surface of the sapphire substrate 11 is the polished surface, the weight average of the first resin portion is 230000 or more, and when the rear surface of the sapphire substrate 11 is the roughened surface, the molecular weight is 160,000 or more. |
