    • An illumination unit includes: one or more light sources, an optical member, and an optical device. The optical member includes an integrator having a first fly-eye lens on which light from a solid-state light-emitting device is incident and a second fly-eye lens on which the light from the first fly-eye lens is incident. The integrator uniformalizes an illuminance distribution of light in a predetermined illumination region illuminated by the light incident from the solid-state light-emitting device. The optical device is disposed on an optical path between the first fly-eye lens and one or more light sources including one or more chips configured by the laser diode, and allows a shape of a luminance distribution of incidence light on an incidence plane of the first fly-eye lens to be expanded along a minor axis direction of the shape of the luminance distribution.
