According to an embodiment of the present invention, a light source unit includes: a light emitting device which emits light; and an optical device that has a first surface having an incident surface to which the light is transmitted, and a second surface which transmits the light to the outside through the incident surface. The first surface includes a recess, which is recessed toward the second surface and forms the incident surface. The second surface includes a recessed part which protrudes from an edge of the first surface and has the center recessed toward a flat surface part. The incident surface includes: the flat surface part which is the highest part of the recess; and a curved part which is extended from the flat surface part to the first surface and forms an opening.
