Abstract:
1. An optical sensor comprising: a plurality of light receiving elements disposed on one surface side of a semiconductor substrate and converting light to an electric signal; a light transparent film disposed on the one surface of the semiconductor substrate and having a light transparent property; a light blocking film disposed on the one surface of the semiconductor substrate via the light transparent film and having a light blocking property; and a plurality of openings disposed in the light blocking film for introducing light into respective light receiving elements, wherein the light receiving elements include a first light receiving element and a second light receiving element, wherein the openings include a first opening corresponding to the first light receiving element and a second opening corresponding to the second light receiving element, wherein a first virtual line is defined so as to extend from a center of the first light receiving element and to pass through a center of the first opening, wherein a second virtual line is defined so as to extend from a center of the second light receiving element and to pass through a center of the second opening, wherein the first virtual line and the second virtual line are different in at least one of an elevation angle and a right-left angle, and wherein a light receiving area of the first light receiving element is larger than an aperture area of the first opening, and a light receiving area of the second light receiving element is larger than an aperture area of the second opening.
