Abstract
An illumination device includes light sources and a light guide member. The light guide member includes an incidence part that guides light emitted from the light sources and entering through an incidence surface towards a center of the light guide member and a central part that has a scattering surface for emitting the guided light towards an illumination target body. The light sources include a first light source facing the incidence surface and a second light source facing the incidence surface and is arranged on the central part's side relative to the first light source. The incidence part has a first curved surface that reflects the light entering through the incidence surface towards the central part and a second curved surface that is arranged on the central part's side relative to the first curved surface and reflects the light entering through the incidence surface towards the central part.
