An optical sensor is attached to a transparent board and includes: a light emitting element that applies light to the transparent board; a plurality of light receiving elements that receive light from the light emitting element, reflected by the transparent board; and a detection unit that detects the amount of rainfall based on output signals of the light receiving elements. The light emitting element applies light to one irradiation region in the transparent board. The light receiving elements correspond to the one irradiation region and the detection unit detects the amount of rainfall based on output signals of the light receiving elements corresponding to the one irradiation region.
