Abstract
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 adhesive layer adheres the substrate to the light transmitting member. The substrate and the light transmitting member 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 second surface of the ultraviolet light emitting element and the light transmitting member in a state of being in contact with the second surface and the light transmitting member. The fluorocarbon compound is in contact with the side surface of the ultraviolet light emitting element. The fluorocarbon compound is not in contact with the adhesive layer.
