A light-emitting device includes a light-emitting element, a substrate supporting the light-emitting element, and one or more lateral wall portions joined to the substrate to surround the light-emitting element. The one or more lateral wall portions includes a first lateral wall portion having a light incident surface configured to receive a light emitted from the light-emitting element and traveling in a first direction and a light exit surface configured to emit the light. The substrate has a joint surface joined to the first lateral wall portion and a lateral surface meeting the joint surface. The lateral surface is located between the light incident surface and the light exit surface in a top view as viewed in a direction perpendicular to the joint surface.
