1. A light-emitting device comprising:
a plurality of light-emitting elements including a first light-emitting element configured to emit first light and a second light-emitting element configured to emit second light;
a photodetector configured to receive a part of light emitted from each of the plurality of light-emitting elements, the photodetector having a first bonding surface;
an optical member having a second bonding surface and a first inner side surface, the second bonding surface being bonded to the first bonding surface of the photodetector, the first inner side surface being continuous from the second bonding surface, and the light emitted from each of the plurality of light-emitting elements being configured to pass through the optical member; and
a bonding portion bonding 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.
