PURPOSE: An optical reflective bead, an optical reflective body, and a method for fabricating the same are provided to improve a self-reflective characteristic of the optical reflective body by coating metal powders on a part of a surface of a bead by a spray coating method. CONSTITUTION: A coating material is formed by mixing aluminium powders with an adhesive transparent resin. A glass bead layer is formed on a flat base layer. Aluminium powders are coated on the glass bead layer by using a spray coating method. At this time, the surface of the bead contacted with the flat base layer is not exposed to the coating material by a shadow phenomenon. Accordingly, the surface of the bead contacted with the flat base layer maintains a transparent state. The adhesive transparent resin is dried by atmosphere or a thermal process.
