Abstract: A light-emitting device includes a plurality of light-emitting elements, a photodetector, an optical member and a bonding portion. The light-emitting elements include a first light-emitting element configured to emit first light and a second light-emitting element configured to emit second light. The photodetector is configured to receive a part of light emitted from each of the light-emitting elements. The photodetector has a first bonding surface. The optical member has a second bonding surface and a first inner side surface. The first inner side surface is continuous from the second bonding surface. The light emitted from each of the plurality of light-emitting elements is configured to pass through the optical member. The bonding portion bonds the photodetector and the optical member with the bonding portion being in contact with the first bonding surface, the second bonding surface, and at least a part of the first inner side surface.
