The method includes carrying out a plasma-etching process using a partly oxidized metal salt film having fine irregular-surface as a resist. In a first step, a metal salt film is formed on the substrate by coating a liquid material containing a metal salt. In a second step, a fine irregular-surface is formed on the metal salt film, and the metal salt film was converted into the resist by the partial oxidization. In a third step, a predetermined irregular-surface is formed on the substrate by carrying out the plasma-etching process to the substrate with the resist.
