Abstract
An optical sensor includes a substrate having a plurality of first light receiving elements in a surface, and a light blocking film having a plurality of first openings. The first light receiving elements are provided such that a direction of travel of incident light defined by each of the first openings is different from a thickness direction of the substrate and form at least one light receiving element set in which an angle of incidence defined between the direction of travel of the incident light and the thickness direction is the same with respect to the light receiving elements. In a view projected in the thickness direction, a positional relationship between the first light receiving elements included in a light receiving element set and the corresponding first openings has rotational symmetry of order 3 or more about an axis along the thickness direction.
