<P>PROBLEM TO BE SOLVED: To provide an optical sensor that suppresses difficulties in detecting the intensity and angle of light by widening directivity. <P>SOLUTION: The optical sensor includes a plurality of light receiving elements formed on one surface side of a semiconductor substrate and converting light into an electric signal, a translucent film formed on one surface of the semiconductor substrate, a light-shielding film formed on the one surface of the semiconductor substrate with the translucent film interposed, and a plurality of openings formed in the light-shielding film and introducing light into the corresponding light receiving elements. A first virtual straight line extending from the center of a first light receiving element to the center of a first opening corresponding to the first light receiving element, and a second virtual straight line extending from the center of a second light receiving element to the center of a second opening corresponding to the first light receiving element are different in at least one of an elevation angle and a right-left angle; and the light reception surface area of the first light receiving element is larger than the opening area of the first opening, and the light reception surface area of the second light receiving element is larger than the opening area of the second opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
