摘要: 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 (120) having a light receiving surface (120a) to receives light, a detector (140) detecting an inclination of the light receiving surface in the vertical direction, and a correction portion (150a) correcting an output signal of the light receiving element (120) based on an output signal of the detector (140). Furthermore, the optical sensor includes a raindrop detector (210) detecting a raindrop, a light detector (230) detecting an incident light, and a storage part (250) storing these things. The raindrop detector (210) includes a light emitting element (211), a first light receiving element (212), and a first lens (213). The light detector (230) includes a second light receiving element (31) and a second lens (33).
