In this research, we propose an edible retroreflector made of candy. Previously proposed edible retroreflector was made of agar, granulated sugar, and water, so it was weak against drying and lost its function in a short period of time. However, solid foodstuffs like candy are stable against drying. Thus, if it was possible to create a retroreflector from candy, longer lifetime is expected to be achieved. Therefore, edible retroreflectors made of candy was developed, and the performances as an optical device were evaluated.
