A rain sensor equipped to a transparent substrate includes a light emitter emitting irradiation lights toward the transparent substrate, light receivers receiving reflected lights of the irradiation lights being reflected on the transparent substrate, a defining section defining an incident angle of each reflected light with respect to each light receiver, and a detection section detecting rainfall amount based on signals output from the light receivers. The light emitter emits the irradiation lights toward an irradiation region defined on the transparent substrate. The irradiation region is divided into multiple detection regions. The detection regions correspond to respective light receivers. The defining section defines the incident angle of each reflected light reflected on the detection region such that each reflected light enters corresponding light receiver. The detection section detects the rainfall amount based on the signals output from the light receivers corresponding to the irradiation regions.
