Abstract
A light emitting module includes a light source, a light guide member, and first and second light reflective members. The light guide member is configured to transmit light from the light source. The light guide member having an upper surface and a lower surface opposite to the upper surface. The first light reflective member is arranged on a lower surface side of the light guide member. The first light reflective member has a lower surface. The first light reflective member includes a first resin, and a first reflective body having a refractive index higher than a refractive index of the first resin. The second light reflective member is arranged on a lower surface side of the first light reflective member. The second light reflective member includes a second resin, and a second reflective body having a refractive index lower than a refractive index of the second resin.
