Abstract:
1. An optical sensor comprising: a light receiving portion; a light emitting portion that emits a light to a transparent plate; a definition portion that defines an incident angle of an incident light that enters the light receiving portion; and a selection portion that selects a wavelength of the incident light, wherein the definition portion and the selection portion share a light shielding film disposed above the light receiving portion with each other, the definition portion has an opening formed in the light shielding film, the selection portion has a slit formed in the light shielding film disposed within a region surrounded by the opening, the light receiving portion has a plurality of light receiving portions, the slit has a plurality of slits corresponding to the plurality of light receiving portions, respectively, wavelengths of incident lights selected by the plurality of slits are different from each other, one of the plurality of light receiving portions is a rain sensor light receiving portion applied to a rain sensor that detects rainfall, in which a reflected light reflected by the transparent plate is incident, the slit corresponding to the rain sensor light receiving portion selects a wavelength bandwidth mainly included in light emitted by the light emitting portion, one of the plurality of light receiving portions is an angle sensor light receiving portion applied to an angle sensor that detects an incident angle of light, and the slit corresponding to the angle sensor light receiving portion selects a wavelength bandwidth except for a wavelength bandwidth mainly included in light emitted by the light emitting portion.
