うに構成してなることを特徴とする雨滴センサ。A light receiving element is installed inside a transparent plate such as a window glass, and a prism is attached to the inner surface of the transparent plate, so that only the light whose optical path is refracted by raindrops etc. adhering to the outer surface of the transparent plate is transmitted from the prism. A raindrop sensor, characterized in that the raindrop sensor is configured such that the light enters the light receiving element.
