Issue to be solved: A lighting device body is provided that can effectively use the light from a light-emitting surface, for example when a wall surface or the like is to be illuminated in a vertically wide range. Solution: A reflector 80 is disposed in an inclined orientation such that the lower portion of an axis C1 is located nearer to a wall surface W. A light-emitting surface 72 of a planar light source 70 is inclined with respect to a first virtual plane H1 that is perpendicular to the axis C1, such that a portion farther from the wall surface W (B portion) is located relatively upper. In other words, the light-emitting surface 72 is oriented toward a region of the reflector 80 located farther from the wall surface W than the axis C1. With this configuration, among the amount of light emitted from the light-emitting surface 72, the amount of light provided to a portion of the reflector 80 farther from the wall surface W is increased.
