PROBLEM TO BE SOLVED: To provide an LED lamp in which heat radiation performance is improved without using a cooling fan.SOLUTION: An LED lamp 100 includes: a substrate 2 having a first surface 21 and a second surface 22 that is a rear surface of the first surface 21; an LED 1 provided on the first surface 21 of the substrate 2; a heat radiation part 3 which is provided so as to contact with the second surface 22 of the substrate 2; a housing 10 which houses the substrate 2, the LED 1, and the heat radiation part 3; and a mouthpiece 8 which is provided at an end part 16 in the housing 10 when viewed in a direction that leads from the first surface 21 of the substrate 2 to the second surface 22. The heat radiation part 3 includes: a first contact surface 32a contacting with the second surface 22 of the substrate 2; and a first extending part 310 which extends in a direction that comes closer to the mouthpiece 8 than the first contact surface 32a and is provided so as to contact with the housing 10. |
