A lighting module disclosed in an embodiment may comprise: a substrate; light-emitting elements on the substrate; a resin layer having a lens portion above the substrate and the light-emitting elements; and multiple recess portions having spaces that distance the lens portion and the substrate from each other, the recess portions sealing the peripheries of respective light-emitting elements. The resin layer may comprise a flat upper surface and a lower surface arranged on the substrate. The lens portion may comprise protruding portions protruding toward the center portions of the light-emitting elements, convex first incident surfaces on the peripheries of the protruding portions, and second incident surfaces extending from the lower portions of the first incident surfaces.
