特徴とする雨滴センサ。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, and light from a light source is irradiated onto the transparent body, so that the optical path of the dazzling light can be used to detect raindrops, etc. attached to the outside surface of the transparent body. In the raindrop sensor, the raindrop sensor is configured such that a light receiving section detects the change when the raindrop changes, and the prism is provided with a surface that restricts external light that has entered the prism from the transparent body from entering the light receiving section. A raindrop sensor characterized by:
