PROBLEM TO BE SOLVED: To provide a light source capable of restraining noises generated by a driving circuit.SOLUTION: The light source comprises: an LED module 20; a support base 30 on which the LED module 20 is located; a driving circuit 40 for emitting light on the LED module 20; a housing 60 that serves as an outline and in which the driving circuit 40 is housed; a circuit holder 50 for holding the driving circuit 40; a mouth piece 70 for receiving power from outside; a heat sink 80 for radiating heat generated during light emission of the LED module 20; and a stable potential line 90 connected to the heat sink 80 so that the heat sink 80 reaches a reference potential of the driving circuit 40. The heat sink 80 has: a main body 81 having a flat plane contacting a second face 31b opposite to a first face 31a that is a face of the support base 30 on which the LED module 20 is located; and a heat radiation fin part 82 communicated with the main body 81 and extending in an interior space of the housing 60. |
