Abstract: The present disclosure provides a retroreflective glass bead that includes at least one high refractive oxide selected from the group consisting of TiO2, BaO, La2O and Bi2O3; and at least one additive selected from the group consisting of MgO, CaO, ZnO, ZrO2, Al2O3, K2O, Na2O, Li2O and SrO. The glass bead according to the present invention have excellent retroreflectivity according to optical properties and excellent durability and productivity due to a simple structure, and also can be produced in various colors due to high chemical stability. Thus, the retroreflective aggregate including the glass bead according to the present invention exhibits very high visibility under various circumstances such as rainy or dry conditions. In addition, the method of producing a glass bead according to the present invention can reduce manufacturing costs while ensuring excellent productivity.
