A semiconductor light emitting element includes: an insulating substrate having a plurality of convex portions on a surface thereof; a plurality of light emitting element components having semiconductor laminated bodies that are laminated on the insulating substrate and are separated from one another by a groove that exposes the convex portions; and a connector connecting between the light emitting element components. The light emitting element components include a first light emitting element component and a second light emitting element component. The first light emitting element component is separated from the second light emitting element component with the groove in between, and has a first protrusion that protrudes toward the second light emitting element component. The connector includes a first connector having a shape that straddles the groove and that follows the convex portions, and has a straight section.
