Zusammenfassung:	A light-emitting element and a light-receiving element are provided on a surface of a substrate. The light-emitting element and the light-receiving element are sealed by transparent resin members and, respectively. A lens is provided at the transparent resin member at a position above the light-emitting element. The center of the lens and a mounting position of the light-emitting element are disposed being shifted from each other. With this, an optical axis of light outputted via the lens is slanted toward an opposite direction side with respect to the light-receiving element at a predetermined elevation angle. In this case, a beam divergence angle of light outputted from the lens is set to a predetermined value.
