Abstract: An optical device includes a protective cover disposed in a field of view direction of an optical sensor, a casing that holds the protective cover, a temperature adjuster that adjusts the temperature of the protective cover, and a vibrating body that drives the protective cover to remove foreign matter adhering to a surface of the protective cover. The temperature adjuster adjusts the temperature of the protective cover so that the temperature increases from the periphery to the center of the protective cover.
