A light emitting device includes a light emitting element, a light-transmissive member, a light guide member and a light reflective member. The light-transmissive member includes a first region directly above a top surface of the light emitting element, and a second region at a lateral side of the first region. The light guide member covers a lateral surface of the light emitting element and a bottom surface of the second region of the light-transmissive member. The light reflective member covers an outer surface of the light guide member. The light-transmissive member contains a fluorescent substance and a light scattering material that is not a fluorescent substance. A concentration of the fluorescent substance in the light-transmissive member is higher in the first region than in the second region. A concentration of the light scattering material in the light-transmissive member is higher in the second region than in the first region.
