    Abstract: A lighting module disclosed in an embodiment comprises: a substrate; a light-emitting element arranged on the substrate; and a resin member arranged on the substrate and the light-emitting element. The resin member comprises a plurality of side surfaces and an exit surface on the upper portion thereof. The plurality of side surfaces of the resin member comprise a first side surface adjacent to the light emitting device, a second side surface facing the first side surface, and third and fourth side surfaces arranged between the first and second side surfaces so as to face each other. The exit surface of the resin member comprises a light extraction structure having a large length in a first direction and having a concavo-convex pattern in a second direction that is perpendicular to the first direction. The light emitting device comprises an exit area corresponding to a part of the second side surface in the first direction. The thickness of the second side surface, in connection with the resin member, may be smaller than the thickness of the first side surface.
