ンサ。A light receiving unit is placed inside a transparent body such as a window glass, and a prism is attached to the inner surface of the transparent body to irradiate light from a light source onto the transparent body and refract or reflect the reflected light to return to the transparent body. A raindrop sensor is characterized in that it is configured such that when the optical path of the dazzling light is caused by raindrops or the like attached to the outer surface of a transparent body, a light receiving section detects this.
