Abstract
A light receiver has a shield wall disposed facing a part of a near-side light-receiving face of a light receiving element from an end opposite from a far-side light-receiving face. The shield wall blocks a portion of reflection light from a detection object located at a distance at which the detection object reflects reflection light that causes an amount of light received by the light receiving element to be larger than or equal to a predetermined value.
