A lighting module disclosed in an embodiment comprises: a plurality of light emitting devices on a substrate; and a reflector arranged in the direction of emission of light from each light emitting device on the substrate. The light emitting device has a light exit surface, and the reflector has a reflecting surface concave toward the substrate, at least a portion of the reflecting surface corresponding to the light exit surface of the light emitting device. The reflecting surface is arranged at a height that increases gradually in proportion to the interval from the light emitting device arranged in the light incident direction. The reflecting surface comprises a plurality of convex portions arranged in a first direction and first bridge portions that connect between the plurality of convex portions. The first bridge portions are arranged along the convex portions and are arranged to be lower than a straight line that connect high points of adjacent convex portions. The convex portions and the first bridge portions have the same length in a second direction, which is perpendicular to the first direction, and the area of the convex portions may be larger than the area of the first bridge portions.
