PROBLEM TO BE SOLVED: To provide a lamp device capable of improving assemblability and easily coping with automatic assembly.SOLUTION: A lamp device 10 includes a housing 11 and a light source unit 12. The housing 11 has a mouth piece 18 on which an electrode pin 17 is disposed. The light source unit 12 has a substrate 41, a light emission element 42 mounted on one face of the substrate 41, a circuit component 44 mounted on the substrate 41, and a connection member 45 electrically connected and fixed to the substrate 41. The connection member 45 is electrically connected to the electrode pin 17 by a screw 52 screwed to the electrode pin 17 through the connection member 45, a region of the other face at a side opposite to the mounting region of one face of the substrate 41 on which the light emission element 42 is mounted, is thermally connected to the mouth piece 18, and the substrate 41 is fixed to the housing 11.SELECTED DRAWING: Figure 1 |
