Abstract:
A light-emitting module includes a light guide member including a first surface, a second surface on an opposite side of the first surface, and a first through hole penetrating from the first surface to the second surface, a light source unit disposed in the first through hole, a first light-transmissive member disposed in the first through hole of the light guide member and covering the light source unit, and a reflective member disposed above the light source unit and disposed above the first light-transmissive member. In a plan view, an outer edge of the reflective member is located outside an outer edge of the light source unit, and the reflective member includes a resin member and a reflector having a refractive index lower than a refractive index of the resin member.
