An illumination device includes a light source section, an optical element, and a driver. The light source section includes a laser light source. The optical element includes a periodic structure, and is disposed in an optical path of light emitted from the light source section. The driver vibrates the optical element to cause a vibration direction to be inclined to a periodic direction of the periodic structure of the optical element.
