The present invention realizes a lighting apparatus having no variation in brightness between a center part and a peripheral part. A lighting apparatus (1) has the following: a substantially disk-shaped main body (2) provided with an opening (10) which receives a fixing means (100) for fixing the lighting apparatus on the installation surface; a reflective cover (12) which covers a part of a main body inner surface (2a); and a plurality of LED units (3) arranged in an annular manner on the main body inner surface (2a) on the outside of the reflective cover. The reflective cover (12) is formed with a flat first reflective surface (12a), a projected second reflective surface (12b), and a recessed third reflective surface (12c). Each LED unit (3) is inclined so that the angle formed by the main body inner surface (2a) and a mounting surface on which an LED element is mounted becomes greater than 90º.
