PROBLEM TO BE SOLVED: To reduce weight and reduce cost of a light source unit as well as improving durability of dies.SOLUTION: A light source unit is provided with a light source part 10 and a socket part 11. The socket part 11 is composed of an insulating member 7, a thermo-conductive resin member 8, power feeding members 91-93, and a metal body 2. As a result, since the light source unit uses the thermo-conductive resin member 8 as a heat radiation member for radiating heat generated in the light source part 10 to the outside, compared with a conventional aluminum die-casting, the light source unit 1 can be made light in weight, its manufacturing cost can be reduced, and durability of dies can be improved. |
