The glass sheet production method of the present invention is a method for producing a surface-modified glass sheet, including a gas contact step of bringing hydrogen fluoride (HF) gas, hydrogen chloride (HCl) gas, and water vapor into contact with at least one principal surface of a glass sheet. A gas containing the hydrogen fluoride (HF) gas is used in the gas contact step, and in the gas containing the hydrogen fluoride (HF) gas, a volume ratio of the water vapor to the hydrogen fluoride (HF) gas (volume of water vapor/volume of HF gas) is 8 or more.
