PROBLEM TO BE SOLVED: To secure a good mounting state of light emitting elements mounted on a substrate and secure a good emissions state of light emitted from the light emitting elements to the outside.SOLUTION: A light source unit includes: a socket housing 9 having engaging parts 20 which are engaged with predetermined members; a light emitting module 11 having light emitting elements 26 functioning as a light source, a substrate 25 including a wiring pattern for supplying electric current to at least the light emitting elements, and a conductive part 28 which connects the wiring pattern with the light emitting elements, the light emitting module 11 disposed in the socket housing; a sealing part 33 which seals the light emitting elements and the conductive part on the substrate; and a lens part 34 formed on the sealing part. An elastic modulus of the lens part is set so as to be higher than an elastic modulus of the sealing part.SELECTED DRAWING: Figure 7 |
