Zusammenfassung:	A vehicle-mounted light source unit (LU) includes a heat sink (80) including a first rib (94L) and a second rib (94R), and a substrate (50) including a first through-hole (51L) and a second through-hole (51R) into which the first rib (94L) and the second rib (94R) are fitted. Each of the first rib (94L) and the second rib (94R) includes an extending portion (94E), and a protruding portion (94P) that protrudes from a part of the extending portion (94E) to a side on which the first rib (94L) and the second rib (94R) approach each other or are away from each other in a left-right direction. Each of the first through-hole (51L) and the second through-hole (51R) includes first facing portions facing both end surfaces of the extending portion (94E) and a second facing portion facing an end surface of the protruding portion (94P).
