Abstract: A light emission module includes a first light emission unit that includes a first light emission device and emits first light. The first light emission device includes a plurality of first light emission portions, each including a light emission surface, where light from a plurality of first light emission elements is emitted, a heat dissipation surface provided opposite to the light emission surface, and a connection portion being positioned between the light emission surface and the heat dissipation surface and including a wiring mounting surface where the light emission elements are electrically connected. The light emission module further includes a first optical member that reflects the first light, a housing including a base member where the first light emission unit and the first optical member are disposed and a lid member surrounding the light emission device surrounding the first light emission unit and the first optical member that are disposed on the base member, and a heat sink being connected to the heat dissipation surface and including a mounting surface where the first light emission device is mounted. The wiring mounting surface extends upward upper than a first upper surface of the housing, and a portion of the wiring mounting surface is exposed to the outside of the housing.
