PROBLEM TO BE SOLVED: To provide a lamp capable of sufficiently insulating an electric circuit board and a body part.SOLUTION: A lamp 1 includes: a base plate 13 on which an LED substrate 16 mounting an LED 15 is placed; a body part 2 integrally formed on a rear surface of the base plate 13 from a material having electric conductive properties; a base 3 connected via an insulation cylinder part 10 having insulation properties provided at a terminal end 2A of the body part 2. It also includes: an electric circuit board 8 accommodated across the body part 2 and the insulation cylinder part 10; and an insulation sheet 28 disposed between the inside surface of the body part 2 and the electric circuit board 8. At a connection side end part 10B of the insulation cylinder part 10 with the body part 2, a projection part 110 extending between the inside surface of the body part 2 and the insulation sheet 28 is formed across the whole periphery.SELECTED DRAWING: Figure 3 |
