To provide a lighting device capable of reduction of the number of components and weight saving of the system as a whole, and yet, capable of aiming at elimination of unpleasant oblique glare while restraining 1/2 beam angle fall.

The lighting device (1) is provided with a substrate (11), at least one point light source (12) arranged on the substrate (11), a diffusion sheet (13) having a low-diffusion area (A1) fitted in an emission direction of the point light source (12) positioned in correspondence to an area including a projection area of the emission face of the point light source (12), and a high-diffusion area (A2) fitted around the low-diffusion area (A1). The device also has a first indented structure for diffusing light from the point light source (12) on a light-incident face and/or light-emitting face of the light of the point light source (12) in the high-diffusion area (A2) of the diffusion sheet (13).
