PROBLEM TO BE SOLVED: To provide a light source device of high productivity and excellent light distribution characteristics. SOLUTION: A plurality of light-emitting diodes 30 manufactured by a transfer mold method are surface-mounted on the lower surface of a substrate 10 using a cream solder. Optical base bodies 20 provided in the radial direction of the light-emitting diodes are integrally provided with a plurality of reflective concave surfaces 21 corresponding to the light-emitting diodes 30 which correspond to the base bodies. The light from the light-emitting diode 30 is reflected on the corresponding reflective concave surface 21, and then converged into an arcuate, in top view, optical opening part 11 formed at the substrate 10. The light is projected outside through the optical opening part 11. |
