Disclosed herein are a light emitting module and a lighting device that may be used for a display application or a lighting application. The light emitting module includes an electrode layer including a plurality of blocks that are insulated from each other by an electrode separating line; and one or more light emitting elements mounted on the electrode layer so as to be electrically connected to any one block of the blocks of the electrode layer and a neighboring block, respectively, wherein the blocks have another neighboring block disposed in a first direction and still another neighboring block disposed in a second direction, based on any one block of the blocks while having the electrode separating line formed to be bent more than once at a predetermined interval therebetween so that heat generated from the light emitting elements is emitted through the blocks.
