Title: PHOTOSENSOR
Abstract:
This photosensor (1) is provided with: a light emitting element (20) which radiates light to an object to be detected; and a light receiving element (40) which has a light receiving surface (40a) that receives the light radiated from light emitting element (20). An incident light regulation part (60), which covers the light receiving surface (40a), is disposed on a light path where the light radiated from light emitting element (20) travels toward the light receiving surface (40a); and the incident light regulation part (60) transmits light that has an incidence angle of less than a predetermined value among the light incident on the light receiving element (40), while blocking light that has an incidence angle of the predetermined value or more.
