The present invention includes a light source portion 10 and a socket portion 11. The socket portion 11 is an integrated structural part which is composed of an insulation member 7, a thermo conductive resin member 8, and electric power feeding members 91 to 93. As a result, according to the present invention, the thermo conductive resin member 8 is used as a heat radiation member to radiate to the outside a heat which is generated at the light source portion 10 and thus it is possible to save the weight of the light source unit 1, save manufacturing costs, and improve durability of a die in comparison with that of a conventional die cast.
