Abstract
An ultraviolet light emitting device includes a substrate, an ultraviolet light emitting element, a bonding layer, a fluororesin film, and a fluorocarbon compound. The substrate includes a mounting surface. The ultraviolet light emitting element includes a first surface, a second surface, and a side surface. The bonding layer bonds the electrode on the first surface of the ultraviolet light emitting element and a part of the mounting surface of the substrate. The fluororesin film is a flexible material configured to transmit ultraviolet light. The substrate and the fluororesin film are disposed in a state where the ultraviolet light emitting element is sandwiched therebetween. The fluorocarbon compound is a liquid at normal temperature and pressure. The fluorocarbon compound fills a gap between the side surface of the ultraviolet light emitting element and the fluororesin film in a state of being in contact with the side surface and the fluororesin film.
