A light emitting module includes a surface emitting panel and an optical member located at the light emitting surface side of the surface emitting panel. The surface emitting panel has a light emitting region and a non-light emitting region. The optical member has a reflector in the region corresponding to the light emitting region. The reflector has a reflectivity distribution in which the average reflectance per unit area varies. According to this configuration, light emitted from the surface emitting panel and guided by the optical member is reflected by the reflector and emitted in front of the non-light emitting region. By this way, a region in front of the non-light emitting region is difficult to be dark, thus allowing the light emission area to be increased. Further, where a number of light emitting modules are arranged in a matrix as a lighting device, a uniform illumination surface is provided.
