PROBLEM TO BE SOLVED: To provide a processing method of glass sheet whereby a precise image can be formed at a low cost without any labor and without lowering the strength of the glass sheet. SOLUTION: The processing method comprises a step wherein a hydrofluoric acid-resistant film 12 is formed on one side of the glass sheet 11, a step wherein a blast-resistant film 13 is formed to form the image on the hydrofluoric acid-resistant film 12, a step wherein the hydrofluoric acid-resistant film 12 and the glass sheet on the part which is not covered with the blast-resistant film 13 is removed by blasting, the glass sheet 11 exposed through blasting is etched with hydrofluoric acid and a step wherein the hydrofluoric acid-resistant film 12 and the blast-resistant film 13 are removed.
