Light emitting module and vehicle lamp

摘要

A light emitting module includes a board on which a plurality of light emitting devices are mounted, a first interconnecting section having first interconnections, one end of each of which being connected to one of an anode side and an cathode side of an associated one of the light emitting devices, a second interconnecting section having second interconnections, one end of each of which being connected to the other of the anode side and the cathode side of an associated one of the light emitting devices, and a power supply portion provided along one side of the board to receive an external power. The second interconnecting section has at least one, but less than the number of the second interconnections, collectively interconnecting portion to which another end of each of the second interconnections is connected.
