A bump structure of a scattering reflective board and a method for manufacturing the bump structure. Multiple strip-shaped shielding sections are arranged on an optical mask at intervals. Multiple irregularly arranged circular holes are distributed in the respective strip-shaped shielding sections. Multiple irregularly arranged circular shielding sections are distributed in spacing sections between the adjacent strip-shaped shielding sections. Multiple irregularly arranged arch notches and arch shielding sections are distributed on the edges of the strip-shaped shielding sections. After exposed and developed, multiple scattered and irregularly arranged bumps are formed on the photosensitive material layer laid on the substrate. Then a reflective film is laid on the substrate and the bumps to form the reflective board.
