An illumination device and a vehicle capable of adjusting the transmittance of light incident on a room and uniformly illuminating the room with illumination light. A lighting device includes a light control member that adjusts the transmittance of incident light, a light control member that is disposed on one surface side of the light control member, and a first surface that is opposite to the light control member. A light guide member 32 provided with a light exit surface at least in part, a light incident surface 32a provided on a surface intersecting the first surface 32b, and causing light incident from the light incident surface 32a to exit from the light exit surface, and a light guide member A light source unit 31 for entering light to a light incident surface 32 a provided in 32, and a first low refractive index layer disposed between the light guide member 32 and the light control member 10 and having a lower refractive index than the light guide member 32. 34.
