A multi-area measuring rain sensor is provided with a reflection plate having different reflection angles, to reflect light emitted from a light emitter along different light paths, thereby measuring an amount or quantity of raindrops through sequential time division of light according to differences of the light paths of the reflected light. In particular, the multi-area measuring rain sensor is capable of forming, at a glass, sensing areas equal in number to a maximum number of light receivers, using light beams split from light emitted from each light emitter while having different reflection angles by the reflection plate, which has different reflection angles to reflect light emitted from the light emitter along the different light paths.
