Abstract: An optical sensor that a deterioration of detecting accuracy is suppressed is provided, and an optical sensor that an increase of the number of components and an increase of a physical constitution are suppressed is provided. The optical sensor has a light receiving element having a light receiving surface to receives light, a detector detecting an inclination of the light receiving surface in the vertical direction, and a correction portion correcting an output signal of the light receiving element based on an output signal of the detector. Furthermore, the optical sensor includes a raindrop detector detecting a raindrop, a light detector detecting an incident light, and a storage part storing these things. The raindrop detector includes a light emitting element, a first light receiving element, (212), and a first lens. The light detector includes a second light receiving element and a second lens.

Abstract: A sunlight lens portion includes a low elevation angle surface for capturing light at low elevation angles, an opposing surface which is adjacent to the low elevation angle surface and which faces a sunlight detection element, and a high elevation angle surface for capturing light at high elevation angles. Further, the sunlight lens portion includes a reflection surface adjacent to the high elevation angle surface and the opposing surface. Accordingly, a portion of sunlight entering the sunlight lens portion is reflected by the reflection surface and guided to the sunlight detection element, therefore it is possible to broaden a range of peak sunlight amount detected by the sunlight detection element. Due to this, it is possible to reduce an effect of the angle of inclination of the windshield on the elevation angle characteristic of the sunlight sensor.
