PROBLEM TO BE SOLVED: To provide a light-emitting device that is practical and has high output and high reliability.SOLUTION: There is provided a light-emitting device including a heat-dissipation member, a wiring substrate portion, a grease layer, a light-emitting element portion, and a structure. The wiring substrate portion is provided on the heat-dissipation member. The grease layer is provided between the heat-dissipation member and the wiring substrate portion, and has conductivity. The light-emitting element portion is provided on an upper surface of the wiring substrate portion. The light-emitting element portion includes a semiconductor light-emitting element emitting first light and a wavelength conversion layer absorbing the first light and emitting second light having a different wavelength from that of the first light. The structure is provided around the light-emitting element portion on the upper surface. |
