PROBLEM TO BE SOLVED: To provide a rain sensor in which a decrease in detection accuracy of raindrops is suppressed.SOLUTION: A rain sensor mounted on a transparent substrate (WS) comprises: a light-emitting element (10) emitting light to the transparent substrate; a light receiving element (20) receiving the light of the light-emitting element reflected by the transparent substrate; and a detection part (30) detecting an amount of rainfall on the basis of an output signal of the light receiving element. The light-emitting element irradiates one radiation region (IR) on the transparent substrate with light, and the plurality of light receiving elements are corresponding to one radiation region. The detection part detects an amount of rainfall based on the output signal of the plurality of light receiving elements corresponding to one radiation region. |
