PURPOSE: A reflective optical sensor for a reflector is provided to integrate light scattered by a light spreading unit at a light receiving unit by arranging light integrating unit between the light spreading unit and the light receiving unit. CONSTITUTION: A reflective optical sensor(30) for a reflector comprises a light transmitting unit(300), a light receiving unit(310), and a light spreading unit(320). The light transmitting unit emits a spot size of optical beam to a target. The light receiving unit comprises a plurality of receiving elements(311,312,313,314,315,316). The light receiving unit is arranged where the optical beam emitted from the transmitting unit is reflected by the target and progresses. The light spreading unit is arranged at an interval from the light receiving surface of the light receiving unit. The light spreading unit transmits and scatters light incoming from the outside, and provides it to the light receiving unit.
