ABSTRACT:
A corner cube reflector includes a two-dimensional arrangement of unit elements. The unit elements are arranged at a pitch of 200 μm or less. As viewed in a direction from which incoming light is coming, each unit element has a peak point and a bottom point. A peak portion, including the peak point, has an excessive portion and/or a missing portion as compared with an ideal peak portion of an ideal corner cube. The level of the peak point is lower than that of the ideal peak point of the ideal corner cube. An average level difference h2between the level of the bottom point and that of an ideal bottom point of the ideal corner cube is smaller than an average level difference h1between the level of the peak point and that of the ideal peak point.
