According to one embodiment, a lighting device includes a base member, a light source on the base member, a light-transmitting cover configured to cover the light source and to emit light emitted from the light source to the outside, and a light guide body provided opposite the light source and configured to guide, to the rear of the light source, at least part of the light from the light source. The cover includes a back light-transmitting region having a plane-normal line directed rearwardly. The light guide body includes a light-incident portion facing the light source and a light guide-emitting portion curvedly extending outward from the light-incident portion, having a distal end portion extending along the back light-transmitting region and directed to the rear.
