Abstract
A light-emitting module of the present invention comprises: a light source in which an LED element is disposed on a substrate and electrodes electrically connected to the LED element are provided on the substrate; a metal plate on which the light source is disposed; lead wires connected to the electrodes directly or via other electrode pattern; and a housing made of resin fixed onto the metal plate and housing the light source therein. Moreover, the housing includes a hole opening above the light source, and includes at least one pair of protrusions that protrude facing one another inside the hole and apply a bias to the light source to press the light source onto a metal plate side.
